Vedclass · Answer

(A) The reducing power is inversely proportional to the standard reduction potential $(E^{\circ}_{red})$. The lower the value of $E^{\circ}_{red}$,the stronger the reducing agent.Among the given values,$Li$ has the lowest potential $(-3.05 \ V)$,so it is the strongest reducing agent.The oxidising power is directly proportional to the standard reduction potential $(E^{\circ}_{red})$. The higher the value of $E^{\circ}_{red}$,the stronger the oxidising agent.Among the given values,$Ag^{+}$ (derived from $Ag$ with $+0.80 \ V$) has the highest potential,so it is the strongest oxidising agent.

According to standard electrode potential,which is the strongest reducing agent and oxidising agent?
$Al (-1.66 \ V), Cu (+0.34 \ V), Li (-3.05 \ V), Ag (+0.80 \ V)$
