A base has a Kb of 2.5 x 10–11. Which of the following statements is true?
This is a concentrated base.
This base ionizes slightly in aqueous solution.
This is a strong base.
An aqueous solution of this base would be acidic.
We don't know how concentrated the base is; the concentration is not stated in the problems.
It has a Kb of 2.5E-11; therefore, #2 is correct. #1 COULD be correct under the right conditions.
