# 10,000ppm hypochlorite

I have to make a solution of 10,000ppm hypochlorite, since 1ppm is like 1mg/l for a solute in water solution. Does this mean that i have to add 10,000mg hypochlorite in 1liter water? If hypochlorite is in a liquid form, should i take into account its density and from that to find the volume i add to the water to get a total of 1 litre?

Besides; Is 1ppm the same like 1mg/l ? Or does it depend in other factors like both the densities of the solute and solvent?

Hope for ideas. THanks.

Yes, you should consider its density to calculate the final mass, from there add the required amount (10.00 mg) to fill up a one liter of solution, which will give you a 10.00 ppm solution.

The one i use is Sodium hypochlorite (NaOCl), with a stock concentration of 12%. Will you please show me how to make 10,000ppm hypochlorite from a 12% stock? It does not have density, i think.

It has density, as every other liquid. However, I can't find a table at the moment :(

If your concentration (12%) is 12 grams of solute in 100 mL of solution, then we know the density. From there, you'll find the concentration as 1.2x105 ppm if you recalculate. Appropriate dilution will give you what you need.

I think you are wrong. Could you show how to calculate the density in such a case?
