Equilibria of Acids and Bases

Question 6 • Foothill-B Period-Chemistry-26/27B

Which statement best relates the strength and concentration of a base?

Answer
A
At high enough concentrations, a weak base becomes strong.
B
Even at low concentrations, a strong base is strong.
C
A weak base always has a low concentration.
D
The stronger the base, the higher its concentration.

Explanation

Base strength describes how completely a base ionizes in water, while concentration describes how much base is present in a given volume. A strong base ionizes extensively even when its concentration is low, so “Even at low concentrations, a strong base is strong” is the best statement. Concentrating a weak base does not make it a strong base.
