% of chlorine in Calcium Hypochlorite
% of chlorine in Calcium Hypochlorite
(OP)
I was wondering how you get the % of availible chlorine in a substance, i've found places that say the % is 65 for calcium hypochlorite, how did they get this number? If I use its atomic weight, it is only about 49.59%. Ca(OCl)2 is the correct formula right?





RE: % of chlorine in Calcium Hypochlorite
Regarding the formula, the product is actually calcium hypochlorite dihydrate so you need to account for 2 waters of hydration. There is also 3-5% excess lime content.
