# Problem: Given that E°cell = 3.20V for the reaction 2Na(in Hg) + Cl2(g) ⇌ 2Na+(aq) + 2Cl−(aq)What is E° for the reduction 2Na+(aq) + 2e−→ 2Na(in Hg)?

###### FREE Expert Solution

We’re being asked to determine the standard reduction potential (E°red) of Na+/Na (inHg) from a reaction occurring in an electrochemical cell. To calculate for the standard reduction potential, use the following equation: When a balanced reaction is given, identify the anode and the cathode half-reactions by determining the changes in oxidation states of each species based on the given reaction:
