Title: Calcium Hypochlorite and Sodium Bisulfate reaction in water?
Post by: BeeThree 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.

Great!

Thanks so much for that.
I'd almost given up hope anyone would reply. 

Really appreciate it!!!
