Question

Quizplus · Accepted Answer

Substances that can act as either an acid or a base are known as amphoteric. Water is the most common example of amphoteric substances. HSO₄^-, on the other hand, is an example of a polyprotic acid that can donate multiple protons. However, since the question mentions it can also accept protons, it can be considered amphoteric as well. Conjugate means a pair of compounds that differ by the addition or removal of a proton, which is not applicable in this case. Therefore, the best choice is A.
