Problem: Treatment of gold metal with BrF3 and KF produces Br2 and KAuF4, a salt of gold.Identify the reducing agent in this reaction.

FREE Expert Solution

Recall the mnemonic for redox reactions:

Loss Electrons → Oxidation → Reducing Agent

Gain Electrons → Reduction → Oxidizing Agent


This means the element that gains electrons/reduced is the oxidizing agent while the element that loses electrons/oxidized is the reducing agent.
