Solution 1

To solve this problem, we need to use the following equations:

  1. pKa + pKb = 14
  2. pKa = -log(Ka)

First, we calculate the pKa from the given Ka:

pKa = -log(4.68 x 10^-5) = 4.33

Then, we substitute the pKa value into the first equation to find pKb:

pKb = 14 - pKa = 14 - 4.33 = 9.67
