Question

1. choose the best answer.

when a(n) ______ agent oxidizes, it causes reduction in another substance.

• reducing
• equating
• oxidizing
• conserving

Explanation:

In redox reactions, a reducing agent is oxidized (loses electrons) and causes another substance to be reduced (gain electrons). An oxidizing agent is reduced and causes oxidation. "Equating" and "conserving" are not relevant terms for this context. So the correct term is "reducing" as the agent that oxidizes itself and reduces another.

Answer:

A. reducing
