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

FREE Expert Solution

We’re being asked to identify the oxidizing agent in the given reaction:

Au + BrF3 + KF  Br2 + KAuF4


To do so, we need to identify the change in oxidation state for each element in the reaction. 

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.
