Answer to Question #288605 in Inorganic Chemistry for BackInLab

Question

So in the lab we got sodium hypochlorite solution. The concentration is in active chlorine (13%) on the label. How do I calculate it to concentration of hypochlorite? I need certain amount of hypochlorite (0,868g aka 0,01166 mole) for the reaction I am trying to do and cause it is not going as described in the article (true, it is from like 1960s but there is nothing newer and their results are way better, like 50% more product) so I am checking if my math on this is right or not.

Thank you for the help and answers in advance

Answer 1

To calculate millilitres of 12.5% sodium hypochlorite (liquid) required to disinfect the water in a tank. For example: To achieve 5 mg/L chlorine in a 1000 litre tank, add approximately 40 mL of 12.5% sodium hypochlorite
