Calcium Hypochlorite and Sodium Bisulfate reaction in water?
« on: April 07, 2010, 05:19:53 AM »
Hi, I am trying to produce HOCl (hypochlorous acid) using Calcium Hypochlorite [Ca(ClO)2] and Sodium Bisulfate [NaHSO4] dissolved in water. 

My problem is that I need the reaction that occurs, and I'm getting some weird answers.

My reaction
2 Ca(ClO)2 + 3 NaHSO4 + 4 H2O --> 4 HOCl + Na2SO4 + CaSO4 + Ca(OH)2 + H2SO4 + NaOH + H2O

I have acids and bases forming, and obviously they can't all form, but I don't know how to predict the right products.
HOCl definitely forms, as well as the CaSO4 (according to other sources), but the rest is guess work.

I would really appreciate any help or suggestions.  I have to use these reagents, so alternate reagent suggestions won't help.

Thanks

Ca(ClO)2 + 2NaHSO4  :rarrow: 2HClO + CaSO4 + Na2SO4

HClO is very unstable it decomposes into HCl and O, the solution have to be chill. pH should be around 7.
