PYQ NEET- Electrochemistry L-2

Question: Standard electrode potentials of three metals $X, Y$ and $\mathrm{Z}$ are $-1.2 \mathrm{~V},+0.5 \mathrm{~V}$ and $-3.0 \mathrm{~V}$ respectively. The reducing power of these metals will be#

A) $Y>Z>X$

B) $Y>X>Z$

C) $Z>X>Y$

D) $X>Y>Z$

Answer: $Z>X>Y$#

Sol:#

More negative the value of reduction potential, stronger will be the reducing agent.

So, $Z(-3.0 \mathrm{~V})>X(-1.2 \mathrm{~V})>Y(+0.5 \mathrm{~V})$
