प्रश्न
Two metallic elements A and B have the following standard oxidation potentials: A = 0·40v B = - 0·80v. What would you expect if element A was added to an aqueous salt solution of element B? Give a reason for your answer.
उत्तर
Since the oxidation potential of A is higher than that of B, therefore, metal A will displace metal B from its salt solution.
