Title: Charge balance and the mass balance
Post by: sheephung on September 25, 2009, 02:14:56 AM

Write the charge balance and the mass balance for the dissociation of sulfuric acid
(H2SO4) to sulphate.

I got charge balance is [H+]=[OH-]+[HSO4-]+2[SO42-]...
but I don't know how to wrong a correct mass balance

My mass Balance is like this
[HSO4-]+2[SO42-]+[H2SO4]=?

Thz
