How to determine a weak base

WebJul 3, 2024 · There are six strong acids. The others are considered to be weak acids. You should commit the strong acids to memory: HCl: hydrochloric acid HNO 3: nitric acid H 2 … 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)
