Consider the reaction: Zn(s) + H₂SO₄(aq) $\rightarrow$ ZnSO₄(aq) + H₂(g) Which species is oxidized, and how many electrons are transferred per atom of zinc that reacts?

Question

Quizplus · Accepted Answer

In this reaction, zinc goes from being neutral (Zn(s)) to having a positive charge (Zn2+(aq)). This means that zinc has lost electrons and is oxidized. The electrons that are lost by zinc are gained by the hydrogen ions in the H₂(aq) species, which are reduced to form H2S(g). Since two electrons are transferred per zinc atom that reacts, the answer is A.
