Question

Quizplus · Accepted Answer

Zinc (Zn) is more reactive than hydrogen and can displace hydrogen in hydrochloric acid, therefore zinc will be oxidized in hydrochloric acid under standard conditions at 25°C. The other metals listed (Ag, Au, Hg, Cu) are less reactive than hydrogen and therefore will not be oxidized in hydrochloric acid under standard conditions.
