Question:

$\text{The strongest reducing agent among the following is:}$

Options:

1. $\text{K}$
2. $\text{Na}$
3. $\text{Al}$
4. $\text{Mg}$

Solution:

$\text{HINT: Alkali metals are the strongest reducing agents.}$ $\text{Explanation:}$ $\text{The ability of a substance to gain electrons is known as reduction potential.}$ $\text{Reducing power of alkali metals increases down the group.}$ $\text{Most of the elements have a certain value of reduction potential. For the given elements, the value of reduction potential will be as follows.}$ $\text{Na} = -2.71 \text{ V, Mg} = -2.38 \text{ V, Al} = -1.66 \text{ V, and K} = -2.92 \text{ V.}$ $\text{The higher the value of electrode potential lower will be reducing power of an element.}$ $\text{Hence, we can conclude that out of the given options K is the strongest reducing agent.}$
