Questions & Step-by-Step Solutions
In the reaction 2Ag⁺ + Zn → 2Ag + Zn²⁺, which species is reduced? (2023)
Step 1: Identify the reactants in the reaction: 2Ag⁺ and Zn.
Step 2: Determine what happens to each reactant during the reaction.
Step 3: Note that Ag⁺ is a positive ion and Zn is a neutral metal.
Step 4: Understand that reduction means gaining electrons.
Step 5: Observe that Ag⁺ gains electrons to become neutral Ag.
Step 6: Conclude that since Ag⁺ gains electrons, it is reduced.
