Expert Solution
Step 1

Given:

Sn2+(aq) +2e- →Sn(s)    E = -0.14 V   -----> (1)

Al3+(aq) + 3e- → Al(s)    E = -1.66 V  ------> (2)

 

since SRP of first reaction reaction is greater than second reaction. which means less negative value is greater than higher negative value.

Higher the SRP value Reduction

lower the SRP value oxidation.
