Write two reactions for NaHCO3, reacting with water in one NaHCO3 is acting as acid the other as a base. Is 0.10M solution going to be acidic or basic? Explain.

Question

I write the two rxns but what do I do with then...

Answer 1

You may be expected to derive the equation for calculating the pH of a 0.1M soln of NaHO3. The shortcut equation is
(H^+) = sqrt(k1k2) or pH =1/2(pK1 + pK2)
