If you have CL2 + H2o ---> H+ + Cl- + HOCl

and you are given [HOCl] = 0.06 M
and you have to find pH....
can you assume that [HOCl] =[H+] = 0.06 M
since H+ and HOCl both have a coefficient of 1?
Thank you

No, you may not assume that BECAUSE HOCl is a weak acid (it has a Ka and it does not ionize completely as dos HCl, HBr, etc).
So if I can't assume that, then how can I calclate pH? I don't know K value, so I can't use Henderson Hasselbalc...
