Question
The dissociation constant of a weak acid HA and weak base BOH are 2 x 10-5 and 5 x 10-6 respectively. The equilibrium constant for the neutralization reaction of the two is (ignore hydrolysis of resuting salt)
Joshi sir comment
HA + BOH ------------------> B+ + A- + H2O
K = [B+][A-][H2O]/[HA][BOH]
= [B+][OH-]/[BOH] * [H+][A-]/[HA] * [H2O]/[H+][OH-] = Kb * Ka / Kw
now solve
