Find the eq. constant for the reaction
CH3COOH (aq) + NO2- (aq) = CH3COO- (aq) + HNO2 (aq)
The Attempt at a Solution
I find Ka for the reaction CH3COOH = CH3COO- + H+ and Kb for the reaction NO2- + H+ = HNO2
But what are the rules then? I try multiplying the constants, but this does not give the correct answer.
