I think its SODIUM MOLYBDATE

The molybdate test is a method used to detect the presence of orthophosphate in water or soil samples. It involves the addition of ammonium molybdate reagent to the sample, which forms a blue complex with orthophosphate ions. The intensity of the blue color is proportional to the concentration of orthophosphate in the sample.

Ammonium molybdate is (NH4)2MoO4. Its molar mass is 148g/mol. A 0.5M solution will have half a mole per liter of water. Half a mole of ammonium molybdate is 74g, so you would measure out 74g of it, and dissolve it in a liter of water.

To prepare 0.5M ammonium molybdate solution, dissolve the appropriate amount of ammonium molybdate tetrahydrate in deionized water and dilute to the desired volume. The molar mass of ammonium molybdate tetrahydrate is 284.95 g/mol, so to make a 0.5M solution, you would need to dissolve 14.25 g of the compound in water and dilute to 1 liter.

The chemical formula for barium molybdate is BaMoO4. It consists of one barium (Ba) atom, one molybdenum (Mo) atom, and four oxygen (O) atoms.

The ammonium molybdate test is a qualitative analytical test used to detect the presence of phosphate ions in a sample. It involves adding ammonium molybdate reagent to the sample, resulting in the formation of a yellow precipitate if phosphate ions are present. The intensity of the yellow color can provide an indication of the concentration of phosphate ions in the sample.

A hydrolysate of casein would likely not give a positive test with ammonium molybdate, as casein hydrolysate molecules are broken down into smaller peptides and amino acids, which may not have the specific chemical groups necessary for the molybdate test to detect. The test with ammonium molybdate typically reacts with phosphorus compounds to form a colored compound, and casein hydrolysate may not contain sufficient phosphorus for a positive result.

Ammonium molybdate is used in the test for phosphorus because it forms a yellow complex with phosphorus, which allows for the colorimetric determination of phosphorus levels. This reaction is commonly used in spectrophotometric methods to quantify phosphorus in various samples.

Methane can be protonated by superacids to the carbonium ion:

H+ + CH4 -> [CH5]+

So methane is a Lewis base but, like helium, it is an exceedingly feeble proton abstractor.

and

They can lose a proton, but their tendency to lose a proton is so small that the term acid would not normally be applied to them.

Ammonium molybdate is not considered a green chemical. It is a chemical compound that is commonly used as a catalyst, reagent, or analytical reagent. However, it has been classified as harmful to the environment and aquatic life, and therefore proper precautions should be taken when handling and disposing of it.

No, wulfenite is not magnetic. It is a lead molybdate mineral known for its vibrant orange to yellow color and forms in a tetragonal crystal system.

To test a urine sample for phosphate ions, you can use a phosphate test strip or a colorimetric method. The test strip changes color in the presence of phosphate ions, providing a semi-quantitative result. Alternatively, a colorimetric method involves adding reagents that react with phosphate ions to produce a colored solution whose intensity can be measured to quantify phosphate levels in the urine sample.

Wulfenite is a lead molybdate mineral that is primarily used as a collector's mineral and in jewelry for its vibrant orange-red color. It is also used in mineral specimens for research and educational purposes due to its distinctive crystal structure. Additionally, wulfenite has limited industrial uses, such as in the production of lead and molybdenum compounds.

Molybdenum, in the form of sodium molybdate, is used in vitamins because it is an essential trace mineral required by the body for normal growth and development. It plays a crucial role in various biological processes, including enzyme function and metabolism. Supplementing with molybdenum helps ensure individuals meet their dietary requirements for this essential nutrient.

Wulfenite is a lead molybdate mineral that does not melt easily but can sometimes be altered by heat. Heating wulfenite quickly can lead to degradation and loss of its crystal structure. It is important to handle wulfenite carefully when exposed to high temperatures.

The Fiske-Subbarow method is a colorimetric assay based on the formation of a blue-colored complex between inorganic phosphate and molybdate. In this method, the reaction between phosphate and ammonium molybdate in an acidic environment leads to the formation of a phosphomolybdate complex, which can be measured spectrophotometrically at a specific wavelength. The intensity of the blue color is directly proportional to the concentration of inorganic phosphate in the sample, allowing for its quantification.

Neutralize a few ml of phosphoric acid and add dilute nitric acid . Then add an equal volume of ammonium molybdate and warm. A bright canary-yellow precipitate is obtained which is soluble in dilute ammonia

Terbium is used as a trace impurity in calcium fluoride, calcium tungstate and strontium molybdate. Terbium is used for a stabilizer in fuel cells when the fuel is used at elevated temperatures.

Molybdenum helps enhance the corrosion resistance of stainless steel (SS316) by increasing its ability to withstand the corrosive effects of chloride ions. This helps prevent the formation of localized pits on the surface of the material, reducing the likelihood of pitting corrosion. Molybdenum also improves the passivation of the stainless steel, which further protects it from corrosion.

Wulfenite typically forms as a secondary mineral in the oxidation zones of lead deposits. It forms when lead-containing minerals are weathered and altered by oxygenated groundwater, leading to the precipitation of lead molybdate. This process often occurs in arid desert environments.

When a phosphate test is carried out and a yellow precipitate is formed upon heating, it is typically due to the presence of ammonium molybdate and a reducing agent (such as ascorbic acid) in the reagent mixture. This yellow precipitate indicates the formation of phosphomolybdic acid, which is a characteristic reaction used to detect the presence of phosphate ions.

Wulfenite is a mineral composed of lead molybdate. It is not commonly used in consumer products due to its lead content, which makes it toxic. Wulfenite is primarily used for mineral collectors and in geological research.

To test for the presence of phosphate (PO4 3-) in water, you can use the molybdenum blue method. This method involves adding ammonium molybdate followed by ascorbic acid and sulfuric acid to the sample, which forms a blue complex in the presence of phosphate ions. The intensity of the blue color is proportional to the phosphate concentration in the water sample.

The principle involved in the test for phosphate in DNA is based on the ability of phosphate ions to form a soluble complex with molybdate ions under acidic conditions. This forms a phosphomolybdate complex that can be detected using spectrophotometry, producing a blue color indicative of the presence of phosphate. This test is commonly known as the molybdenum blue assay.

There could be no difference, or every difference. The color of an anti-freeze is no indication of its chemical makeup, it's only a dye added to make spotting leaks easier.

You'll have to read your owner's manual to determine if it is safe to use various types of coolants, as using the wrong coolant can destroy your engine.

For instance, if you have a small scooter or motorcycle engine that uses certain types of gaskets, and you use coolant that contains 2-ethylhexanoic acid (also known as sodium 2-ethyl hexanoate), the coolant can literally dissolve your gaskets, causing coolant to leak into the combustion chamber or into the oil. And unless you catch it right away, the engine will be destroyed.

Another instance, if your water pump mechanical seals are not designed to handle silicate-based coolants (usually the plain old ethylene glycol or propylene glycol coolants), the silicates can destroy the water pump mechanical seals, leading to coolant leaks. Again, if the low coolant level isn't caught right away, the engine will be destroyed.

Another instance, if you have an older coolant system that isn't perfectly air-tight (usually the older systems without an expansion tank to catch coolant overflow), as the coolant expands as it is heated, it will push some of the coolant out of the radiator. When it then cools and contracts, it will suck in some air. If you're using the new Organic Acid Technology coolants (usually potassium 2-ethyl hexanoate or sodium 2-ethyl hexanoate containing coolants), the air will react with the coolant, causing it to sludge up and plug your coolant passages. Again, if this isn't caught right away, it can destroy your engine.

So your best bet is to figure out what metals are in your system (and the metals can include magnesium, aluminum, low-lead solder, high-lead solder, copper, mild steel, cast iron), then research which chemicals are best for protecting those metals:

----------

Aluminum corrosion is best inhibited by silicate and most poorly by phosphate and borate.

Cast aluminum corrosion is best inhibited by silicate and most poorly by phosphate and molybdate.

Copper corrosion is best inhibited by molybdate and most poorly by benzoate.

High-lead solder corrosion is best inhibited by molybdate and phosphate and most poorly by nitrate, silicate and benzoate.

Low-lead solder corrosion is best inhibited by tolytriazole and molybdate and most poorly by nitrate and silicate.

Mild steel corrosion is best inhibited by molybdate, phosphate and nitrite and most poorly by tolytriazole and benzoate.

Gray cast iron corrosion is best inhibited by nitrate and most poorly by benzoate, tolytriazole, and borate.

----------

Then you need to figure out if your water pump mechanical seals can handle silicate-based coolant if you have aluminum in your system.

Negatively stained samples are typically stained with acidic dyes such as India ink, nigrosin, or uranyl acetate. These dyes have a contrasting effect, allowing the visualization of the background while leaving the sample unstained.

The molybdenum blue method for determining phosphates involves reacting phosphates with ammonium molybdate and ascorbic acid in acidic conditions to form a blue complex. The intensity of the blue color is proportional to the concentration of phosphate in the sample, which can be measured spectrophotometrically at a specific wavelength. Calibration curves are typically used to quantify phosphate concentrations based on the absorbance values obtained.

To test for nitrates in water, you can use a nitrate test kit that typically involves adding reagents to a water sample and observing a color change to determine nitrate levels. For phosphates, a phosphate test kit can be used following similar steps of adding reagents to a water sample and observing color changes. Both tests are based on chemical reactions specific to nitrates and phosphates, allowing for their quantification in water samples.

To measure calcium and phosphate using a spectrophotometer, you would need to use specific reagents that can form colored complexes with these ions. For calcium, you can use a chromophore such as o-cresolphthalein complexone, which forms a purple complex in the presence of calcium ions. For phosphate, you can use reagents such as ammonium molybdate and ascorbic acid, which form a blue complex with phosphate ions. By measuring the absorbance of these colored complexes at specific wavelengths using a spectrophotometer, you can quantify the concentrations of calcium and phosphate in your sample.
