An aqueous solution contains 1.0 M of X ²⁺ and 0.001 M of Y ²⁺ ions at 25^ C . X ²⁺ and Y ²⁺ ions do not interact with each other. This solution is put in an electrolytic cell and the voltage is gradually increased till a current begins to flow through the cell. The voltage is maintained at this point and a deposit is observed on the cathode. What is the composition of the material deposited on the cathode? (Given: A
