Problem: Heart pacemakers are often powered by lithium-silver chromate "button" batteries. The overall cell reaction is:2Li(s) + Ag2CrO4(s)  →  Li2CrO4(s) + 2Ag(s)Write the anode reaction.

FREE Expert Solution

We’re being asked to indicate the half-reactions occurring at the anode.


2 Li(s) + Ag2CrO4(s)  →  Li2CrO4(s) + 2 Ag(s)


We’ll identify the anode and cathode half-reactions using the following steps.

Step 1. Separate the overall reaction into two half-reactions
Step 2. Separate the compound to ions
Step 4. Determine the oxidation half-reaction and the reduction half-reaction. 
Step 5. Identify the anode and cathode half-reaction.


Step 1. Separate the overall reaction into two half-reactions
