Solution: It would not be wise to store a chromium(III) nitrate solution in an aluminum container. Why?a. Cr3+ is a stronger reducing agent than Al 3+b. Al3+ is a stronger oxidizing agent than Cr3+c. Al is a stronger reducing agent than Crd. Cr is a stronger oxidizing agent than Al

Problem

It would not be wise to store a chromium(III) nitrate solution in an aluminum container. Why?

a. Cr3+ is a stronger reducing agent than Al 3+

b. Al3+ is a stronger oxidizing agent than Cr3+

c. Al is a stronger reducing agent than Cr

d. Cr is a stronger oxidizing agent than Al

Solution

Loss of Electron is an Oxidation process undergone by the Reducing Agent (LEORA)

Oxidation happens in the Anode where the E° value is smallest


Gain of Electron is a Reduction process undergone by the Oxidizing Agent (GEROA)

Reduction happens in the Cathode where the E° value is largest
