Predicting the qualitative acid-base properties of salts Consider the following data on some weak acids and weak bases: acid base Ka K, name formula name formula -4 hydrocyanic acid HCN 4.9 x 10-10 methylamine CH;NH, | 4.4 × 10 -4 hypochlorous acid HC1O 3.0 x 10-8 ethylamine C,H;NH, 6.4 × 10* 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 solution that will have the next lowest pH, and so on. solution pH 0.1 M NACN choose one v 0.1 M C2H5NH3Br choose one v 0.1 М KCIO choose one v 0.1 M NaNO3 choose one v
