A) The anions that are conjugate bases of strong acids are strong bases.
B) The acid-base behavior of anions of polyprotic acids is independent of the extent of deprotonation.

D) Basic anions are conjugate bases of acidic cations.
E) Basic cations are conjugate bases of weak acids.

Question

Quizplus · Accepted Answer

Alkali metal (Group 1) and alkaline earth metal (Group 2) cations, due to their low charge density and inability to significantly attract water molecules, do not hydrolyze in solution. Therefore, they have no measurable effect on the pH of a solution.
