## What is the cell potential of magnesium?

Standard Electrode Potentials in Aqueous Solution at 25°C

Cathode (Reduction) Half-Reaction Standard Potential E° (volts)
Ca2+(aq) + 2e- -> Ca(s) -2.76
Na+(aq) + e- -> Na(s) -2.71
Mg2+(aq) + 2e- -> Mg(s) -2.38

How do you calculate cell potential?

The overall cell potential can be calculated by using the equation E0cell=E0red−E0oxid. Step 2: Solve. Before adding the two reactions together, the number of electrons lost in the oxidation must equal the number of electrons gained in the reduction. The silver half-cell reaction must be multiplied by two.

## How do you calculate electrochemical cell potential?

1. At the standard state.
2. Write the half-reactions for each process.
3. Look up the standard potential for the reduction half-reaction.
4. Look up the standard reduction potential for the reverse of the oxidation reaction and change the sign.
5. Add the cell potentials to get the overall standard cell potential.
