Predicting the quam Consider the following data on some weak acids and weak bases: name shift acetic acid hydrofluoric acid acid solution. 0.1 M CsHsNHBr 0.1 M NaCH3CO₂ 0.1 M NaCl 0.1 M KF 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.
