Similarly,aqueous solutions of sodium or calcium hypochlorite will hydrolyze according to: Ca(OCl) 2 + 2H 2 O → Ca 2+ + 2HOCl + 2OH— NaOCl + H 2 O → Na + + HOCl + OH— The two chemical species formed by chlorine in water, hypochlorous acid (HOCl) and hypochlorite ion (OCl—), are commonly referred to as “free available”chlorine.

Sodium ,hypochlorite, (bleach) and ,calcium hypochlorite, (granular chlorine) will raise the liquid pH and alkalinity while performing as disinfectants. Care must be taken when using these chemicals, not only because of their very high pH and corrosive effects, but also because of the dangerous ,chemical, reactions that occur when they are added to low-pH liquids and biosolids.

24/9/2009, · Sodium ,hypochlorite, or ,calcium hypochlorite, is basically chlorine gas dissolved into a watery alkaline solution. If you destroy the alkalinity by adding ,acid,, you destroy the liquid's ability to keep the chlorine gas in solution, and it is all suddenly released as an inhaleable gas.

Depending on the pH value, underchloric acid partly expires to hypochlorite ions: Cl 2 + 2H 2 O -> HOCl + H3O + Cl-HOCl + H 2 O -> H 3 O + + OCl-This falls apart to chlorine and oxygen atoms: OCl--> Cl-+ O Underchloric acid (HOCl, which is electrically neutral) and hypochlorite ions (OCl-, electrically negative) will form free chlorine when bound together.

Calcium Hypochlorite Calcium hypochlorite, is a white free-flowing granular powder or solid cake. Its common name is high test ,hypochlorite, (HTH), which is commonly used for swimming pool chlorination. Available chlorine content is 65 to 70%. It is stable and can be stored for long periods of time with only a small loss of strength.
