WebAug 1, 2024 · It is the ratio of the equilibrium concentrations of the dissociated ions and the acid. The dissociation reaction of the CH3COOH acid would be as follows: CH3COOH = CH3COO- + H+ The acid equilibrum constant would be expressed as follows: Ka = [H+][CH3COO-] / [CH3COOH] = 1.8× 10^–5. To determine the equilibrium concentrations … WebForming this bond that we get H3O plus. So another way to write this acid base reaction would be just to write acetic acid, CH3, COOH plus H2O gives us the acetate anion, CH3COO minus plus H3O plus. Now acetic acid is a weak acid and weak acids don't donate protons very well. So acetic acid is gonna stay mostly protonated.
