Chemistry Practice Problems Redox Reaction Practice Problems Solution: Decide whether or not Au dissolves in 1 M HIO3.

Solution: Decide whether or not Au dissolves in 1 M HIO3.

Problem

Decide whether or not Au dissolves in 1 M HIO3.

Solution

Establish the half-reactions involved with HIO3 and Au and determine if HIO3 is capable of dissolving (oxidizing) Au (s)

Reactions with higher (more positive) reduction half-cell potential has a greater tendency to gain electrons (reduce) and act as oxidizing agent

The half-reactions of HIOand Au will appear as:
