Chapter 21, Problem 69IAE

Interpretation Introduction

Interpretation:

To calculate the minimum voltage required to electrolyze ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}$.

Concept introduction:

Use below formula to calculate the voltage required as follows:

$\Delta G°=-nF{E}_{\text{cell}}^0$ .......(1)

Here, n represent electron transfer, F and $E_{\text{cell}}^0$ represent faraday constant and cell potential respectively.
