It is a highly corrosive, strong mineral acid with many industrial uses. Hydrochloric acid is found naturally in gastric acid. It is a member of the binary acids. Why is HF a weak acid, when the rest of the hydrohalic acids are strong? WebAug 14, 2024 · For example, nitrous acid ( HNO2 ), with a pKa of 3.25, is about a million times stronger acid than hydrocyanic acid (HCN), with a pKa of 9.21. Conversely, smaller values of pKb correspond to larger base ionization constants and hence stronger bases.
