Predicting the qualitative acid-base properties of salts Consider the following data on some weak acids and weak bases: base acid K а K₁ name formula name formula hydrofluoric acid HF -4 6.8 × 10 hydroxylamine HONH2 1.1 × 10¯ 8 hydrocyanic acid HCN 10 4.9 × 10 methylamine CH3NH2 | 4.4 × 10¯ 4 Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. solution pH 0.1 M KCN 0.1 M CH3NH3Br 0.1 M HONH3Cl choose one v choose one choose one v 0.1 M NaBr choose one v 6
