Among the following species, which is the strongest oxidising agent?

Options

A. `Ti^(2+)(aq)`
B. `Zn^(2+) (aq)`
C. `Cu^(2+) (aq)`
D. `Fe^(2+) (aq)`

Answer

C

Explanation

The high energy required to transform `Cu(s) " to " Cu^(2+)(aq) i.e, Delta_a H^theta` is not balanced by its `Delta_(hyd)H^theta`
