To make a 1000 ppm copper standard solution, dissolve 1 gram of copper salt (such as copper sulfate) in 1 liter of distilled water. Dilute the solution accordingly if a different volume is desired. This will result in a solution where 1 milliliter contains 1 milligram of copper.
"Take 8.6339 g of ferric ammonium sulphate and dissolve it in 1 L of water"
Actually this answer is wrong. You are making an elemental standard, not a compound standard. You are only looking for IRON.
Therefore the calculation is:
1000 ppm = 1000 mg / L Fe * 1 g Fe / 1000 mg Fe * 392.14 g FeX/55.845g Fe * 1 L = 7.02194 grams
Since the MW of Ammounium iron sulphate hexahydrate is 392.14
MW of Elemental Iron is 55.845
There is a conversion factor of 392.14/55.845, which gives you a total of 7.02194 grams if you make one liter. That will change if you have less than one liter for instance 250 mL = 0.25L * 7.02194 = X grams.

How do you make Copper II Chromate?
Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
Why aqueous solution of copper sulphate is acidic in nature?
Aqueous solutions of copper sulfate are acidic because of the presence of hydrogen ions (H+) in the solution. When copper sulfate dissolves in water, it undergoes hydrolysis, releasing hydrogen ions which make the solution acidic.
How will you obtain pure copper sulphate crystal?
To obtain pure copper sulfate crystals, you can start by dissolving copper sulfate in water to form a saturated solution. Then, allow the solution to cool slowly, which will encourage the formation of crystals. Finally, filter the solution to separate the crystals from the remaining liquid and allow the crystals to dry to obtain pure copper sulfate crystals.
Insoluble base used to make copper sulfate?
Sodium hydroxide (NaOH) is an insoluble base that can be used to make copper sulfate. When sodium hydroxide is added to a solution of copper sulfate, a blue precipitate of copper hydroxide forms. This precipitate can be filtered and then reacted with sulfuric acid to produce copper sulfate.
How do you prepare a primary standard solution of 0.0500 M sodium carbonate?
To prepare a 0.0500 M sodium carbonate solution, you would need to accurately weigh out the required amount of anhydrous sodium carbonate (Na2CO3), dissolve it in a known volume of water, and then dilute to the appropriate final volume while ensuring thorough mixing to achieve homogeneity. Make sure to use appropriate glassware and techniques to maintain accuracy.
How do you make 1000ppm standard of Na using the salt NaCl?
To make a 1000 ppm Na standard solution using NaCl, you would dissolve 0.0585 grams of NaCl (molecular weight of NaCl = 58.44 g/mol) in 1 liter of water. This would give you a solution with a concentration of 1000 ppm Na.
Does copper make a solution of green color?
blue
How many mls of 1000ppm needed to make 1litre of 1000ppm?
To make 1 liter of a 1000 ppm solution from a 1000 ppm stock solution, you would need 1 ml of the stock solution. This is because 1 ml of the 1000 ppm stock solution contains 1000 parts of solute in 1 million parts of solution, which is equivalent to 1 liter.
How do you prepare 1000 ppm chloride solution from NaCl?
What volume of this solution do you desire? Let's say you want to make 1 liter of such a solution. You would weigh out 1 gram (1000 mg) of NaCl and dissolve it in enough water to make a final volume of 1 liter (1000 ml). Since 1000 ppm means 1000 mg/liter, this is how you make 1 liter of that solution. For larger or smaller volumes, adjust appropriately.
What is standard solution in titration?
A standard solution in titration is a solution of known concentration that is used to determine the concentration of another solution. It is typically a primary standard that can be accurately weighed and dissolved to make a solution of precise concentration. Standard solutions are essential in titration to accurately measure the volume of the solution being titrated and calculate its concentration.
What is the reaction when water mix with copper sulfate?
Mixing these two reagents would make a dilute solution of copper sulfate.
What green powder do you add to dilute hydrochloric acid to make copper chloride solution and carbon dioxide?
You would add powdered copper carbonate to dilute hydrochloric acid to produce copper chloride solution and carbon dioxide gas.
What ratio of hydrated lime copper sulphate is needed to make 15 liters of solution?
Depending on the desired concentration of the solution !
What else do you need apart from oxygen to make CuCO3?
Copper and carbon along with oxygen make up copper(II) carbonate. However you cannot make it simply by mixing them together. A possible pathway might be to get to sodium carbonate perhaps CO2 + NaOH might be the way and then make some copper sulfate by reacting it with H2SO4, mix your sodium carbonate solution with copper sulfate solution and copper carbonate should precipitate out.
How do you make Copper II Chromate?
Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
When combining copper and tin to make bronze how can you increase the solubility of the solution?
increase temperature
How do you make pure copper?
Pure copper can be made by electrolyzing a copper sulfate solution using copper electrodes. During this electrolysis process, copper ions in the solution migrate towards the negative electrode and deposit as solid copper, resulting in pure copper being formed. It is important to use high-purity chemicals and maintain controlled conditions to ensure the purity of the final copper product.
