Question

Electrode potentials for the general reaction, $M_{(aq)}^{3+}+3e^{-}⟶M_{(s)}$ are given below. $M$ belongs to group $13$. The electrode potential of the most electropositive metal among the given is _____.$V$

Metal	$M_1$	$M_2$	$M_3$	$M_4$
Electrode potential $(V)$	$-0.56$	$-1.66$	$+1.26$	$-0.34$

Answer 1

Answer: -1.66

Larger negative electrode potential, greater is the tendency to lose electrons and thus, greater is the electropositivity.
