Web1 Answer Sorted by: 5 Since p K a + p K b = 14, you get p K a = 10.64 for the methylammonium cation. H C l protonates methylamine. The amount of methylammonium increases by the same amount methylamine decreases. So p K a = p H + log ( [ H A] [ A X −]) = p H + log ( x 10 m m o l − x) WebFeb 9, 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified.
