Solution
The weakest base is represented by the smallest Kb value. The smaller the Kb, the less the base ionizes, and the weaker it is.
Looking at the options:
A. Kb = 7.41 x 10^-5 B. Kb = 1.8 x 10^-5 C. Kb = 1.26 x 10^-6 D. Kb = 3.8 x 10^-10
The smallest Kb value is 3.8 x 10^-10.
So, the weakest base is represented by option D. Kb = 3.8 x 10^-10.
