Molecules or ions that can alternately behave as either a Brønsted-Lowry acid or base are called
A) polyanions.
B) hydronium ions.
C) polyprotic acids or bases.
D) conjugate acids or bases.
E) amphiprotic.

Question

Quizplus · Accepted Answer

The correct term for molecules or ions that can behave as both a Brønsted-Lowry acid or base is amphiprotic. The other answer choices do not accurately describe this property. Polyanions are molecules with multiple negatively charged ions, hydronium ions are protonated water molecules, polyprotic acids or bases are molecules that can donate or accept multiple protons, and conjugate acids or bases refers to the paired molecules that are formed during an acid-base reaction.
