The ppm (parts per million) of sodium sulphide would depend on the concentration of sodium sulphide in the solution. To calculate the ppm, you would need to know the mass of sodium sulphide dissolved in a known volume of solution. This would allow you to determine the amount of sodium sulphide in relation to the total volume of the solution.

What is 24 percentage of sodium chloride in ppm?
Percent = per 100,ppm = parts per million = per 1,000,000So 24 / 100 = 240,000 / 1,000,000 (count number of non-bolded italiczero's!)24% = 240,000 ppm
How do you prepare 100 ppm fluoride standard from sodium fluoride?
To prepare a 100 ppm fluoride standard from sodium fluoride, you would dissolve an appropriate amount of sodium fluoride in a known volume of water. For example, to make 1 liter of 100 ppm fluoride solution, you would dissolve 0.1 grams of sodium fluoride in 1 liter of water.
What is the concentration in ppm of sodium fluoride in tap water that has been fluoridated by the addition of 32 of for every 20 of solution?
The concentration of sodium fluoride in the tap water is 76 ppm. This calculation is based on the ratio provided, where for every 20 parts of solution there are 32 parts of sodium fluoride added.
Is 100 ppm solution of NaCl means 100 ppm of Na?
No, a 100 ppm NaCl solution means there are 100 parts per million of NaCl (sodium chloride) in the solution, not just sodium (Na) alone. To calculate the amount of sodium ions (Na+) in the solution, you would need to consider the molar mass of NaCl and the percentage of Na+ in NaCl.
How can you prepare 1ppb from1000ppm sodium standard?
To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
What atoms do sodium sulphide contain?
Sodium sulphide has one sodium atom and two sulphur atoms. NA2S
What is the formula of sodium sulphide?
Na(2)S
What is 24 percentage of sodium chloride in ppm?
Percent = per 100,ppm = parts per million = per 1,000,000So 24 / 100 = 240,000 / 1,000,000 (count number of non-bolded italiczero's!)24% = 240,000 ppm
How do you prepare 50 ppm Na from Na-Cl?
Sodium is separated from sodium chloride by electrolysis.
How do you prepare 100 ppm fluoride standard from sodium fluoride?
To prepare a 100 ppm fluoride standard from sodium fluoride, you would dissolve an appropriate amount of sodium fluoride in a known volume of water. For example, to make 1 liter of 100 ppm fluoride solution, you would dissolve 0.1 grams of sodium fluoride in 1 liter of water.
What is the concentration in ppm of sodium fluoride in tap water that has been fluoridated by the addition of 32 of for every 20 of solution?
The concentration of sodium fluoride in the tap water is 76 ppm. This calculation is based on the ratio provided, where for every 20 parts of solution there are 32 parts of sodium fluoride added.
How 1000 ppm solution of arsenite prepared from sodiumarsenite?
To make a 1000 ppm solution of arsenite from sodium arsenite, you would need to dissolve a specific amount of sodium arsenite in a known volume of solvent. The formula for calculating parts per million (ppm) is: ppm = (mass of solute / mass of solution) × 1,000,000. Determine the mass of sodium arsenite needed using this formula and then dissolve it in the desired volume of solvent to achieve a 1000 ppm arsenite solution.
What is the word equation for the reaction of sodium plus sulfur?
The word equation for the reaction of sodium plus sulfur is "sodium + sulfur → sodium sulfide."
How do you prepare 1000 ppm sodium nitrite solution?
To prepare a 1000 ppm sodium nitrite solution, you would need to weigh out the appropriate amount of sodium nitrite powder and dissolve it in a specific volume of water to achieve a concentration of 1000 ppm (parts per million). For example, to make 1 liter of a 1000 ppm sodium nitrite solution, you would dissolve 1 gram of sodium nitrite in 999 milliliters of water.
Is 100 ppm solution of NaCl means 100 ppm of Na?
No, a 100 ppm NaCl solution means there are 100 parts per million of NaCl (sodium chloride) in the solution, not just sodium (Na) alone. To calculate the amount of sodium ions (Na+) in the solution, you would need to consider the molar mass of NaCl and the percentage of Na+ in NaCl.
How much sodium chloride to add to create 29 ppm sodium?
The answer is 11,5 mg NaCl for 1 L water.
How do you prepare 5 ppm sodium hydroxide solution?
To prepare a 5 ppm sodium hydroxide solution, you would need to dissolve a small amount of sodium hydroxide in a larger volume of water. For example, to make 1 liter of 5 ppm solution, you would add 5 mg of sodium hydroxide to the water. It's crucial to accurately measure both the sodium hydroxide and the water to ensure the final concentration is correct.
