6th Edition 12.39

When identifying the Kb values of these molecules, why can we use the same values if the molecule is not exactly the same? For example, question 2 is not exactly the same molecule as the one whose pB we use to find the Kb value.

The same values of the molecules can be used because in order to find the Ka you would be able to use the equation Ka +Kb= 1x10^-14 since the Kb value has been provided. This would also be applied if the Ka were to be provided in order to find the Kb.
