pH Reduction of Sodium Hypochlorite Solutions using CO 2 Addition. Household sodium hypochlorite (bleach) normally maintains a pH from 12.0-13.5. Grocery store chains, discount stores, pool suppliers, and other points of distribution often require environmental hazardous cleanup with spillage of bleach having a pH greater than 12.
I’m putting this is the chlorine section because that is the only thing I have added to the pool since I opened it, not counting the spring opening kits from Leslies. My concern is really about PH. Will sodium hypochlorite raise the PH level, all other things being equal? I ask because the PH has risen from 7.6 to 7.8. The only other thing I know of that has entered the pool is some rain on ...
Sodium hypochlorite is the main ingredient in household bleach as well as in some of the pool sanitizers you use. Most commonly, liquid chlorine is made of this compound. But a lot of the liquid chlorine you buy for pools contains calcium hypochlorite instead.

Sodium hypochlorite solutions are packaged with vented closures. Do not use containers which are leaking or show evidence of having leaked.
On June 28th, if you recall, we discussed with pool/spa water chemistry expert Richard Falk the impact of sodium hypochlorite on pH in our piece titled “Liquid Chlorine Raises pH, or Does it? Richard explained that the pH rise folks typically experience in swimming pools comes from the outgassing of carbon dioxide, and not from hypochlorites.
In most cases, Iron, nickel, copper, and other heavy metal ions that catalyze bleach decomposition are below detectable levels. The continuous process equipment provides low manufacturing temperature without localized overheating. Continuous process sodium hypochlorite also has quality in terms of concentration, ratio, pH, and excess alkalinity.
sodium hypochlorite is a chemical compound with the formula NaOCl.Sodium hypochlorite solution, commonly known as bleach, is frequently used as a disinfectant and as a bleaching agent. Liquid chlorine; usually provides 10% to 12% available chlorine; has a pH of 13 and requires that small amounts of acid be added to the pool to neutralize the high pH.
