Question

e° of cu and zn are 0.34V and -0.76V respectively. which of them is strongest reducing agent ​

Answer 1

Answer:

See below.

Explanation:

We are given,

$\begin{aligned}E^{0}\left( Cu^{2+}\right) =0.34V\\ E^{0}\left( Zn^{2+}\right) =-0.76V\end{aligned}$

Greater the eletrode potential, greater is the tendency of the cation to get reduced. Cations which reduce quickly are stronger oxidizing agents, so weaker cations ( which do not reduce quickly ) are better reducing agents.

Among Cu2+ and Zn2+, Zn2+ does not reduce as readily as Cu2+. So, as explained above, Zn2+ is the better reducing agent.
