Web22 apr. 2024 · A 0.45 M solution of a weak acid, H X, has a p H of 4.5. What is the ionization constant, K a, of the acid? [ H X] is already given as 0.45 M. [ H X +] is given by 10 − 4.5. Since p H is 4.5, p O H = 14 − 4.5 = 9.5. Then we can get [ O H X −] by computing 10 − 9.5. Then computing K a, I get 10 − 4.5 ⋅ 10 − 9.5 0.45 = 2.22 × 10 − 14.
