The dissociation constants of monobasic acids A, B, C and D are 6 × 10 –4, 5 × 10 –5, 3.6 × 10 –6 an — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

From the dissociation constants, it is clear that the strength of the acids is in the order A > B > C > D. All the acids have been taken at the same concentration however the H in all the solutions will not be the same as the extent of dissociation in each case will be different. The stronger the Ka value, the more it will dissociate therefore it will produce a larger H . pH of its solution will be lower. pH will follow order A < B < C < D.
