Question

Consider the following data on some weak acids and weak bases acid base name formula name formula acetic acid HCH CO x 10 ammonia NH 18x 10 hydrofluoric acidHF 6.8 x 10 ethylamine C2HNH2 6.4 x 10 Use this data to rank the following solutions in order of increasing pH. In other words, select a ' the solution that will have the next lowest pH, and so on next to the solution that will have the lowest pH, a '2' next to solution pH 0.1 M C2HsNH3Br 0.1 M NH4CI 0.1 M NaNO3 choose one choose one choose one 0.1 M KCH3CO2 choose one
