12.39 and 12.41

[Douglas Nguyen 2J]

12.39: Using data in Tables 12.1 and 12.2, place the following acids in order of increasing strength: HNO2, HClO2, +NH3OH, (CH3)2NH2+"

How would you go about solving this problem? I referred to the table in the textbook and got the values for HNO2 and HClO2, but the last two aren't listed. What method would you use to determine their strengths?

The other two acids aren't on the table because they're the conjugate acids of certain bases that can be found on Table 12.2. By using the relationship of Kw = Ka * Kb, you can convert between the acid constant and the base constant to determine the relative strengths.
