Two metallic elements $A$ and $B$ have the following standard oxidation potentials:
$A = 0.40 V B = - 0.80 V$ . What would you expect if element $A$ was added to an aqueous salt solution of element $B$ ? Give a reason for your answer.

Solution

Metal $A$ will displace metal $B$ from its salt solution because oxidation potential of $A$ is higher than that of $B$ .
