AgNO3 solution and copper metal
D
ZnSO4 solution and aluminium metal
Solution
Verified by Toppr

Copper is more reactive than silver hence displaces silver from silver nitrate solution. Aluminium is more reactive than zinc hence displaces zinc from zinc sulfide solution.

A student was given two metal strips X and Y alongwith colourless silver nitrate solution to perform two separate displacement reactions. When the student placed metal strip X in silver nitrate solution for a considerable time, he observed that the solution turned blue and a coating of silver metal was formed on the strip. And when the student immersed metal strip Y in silver nitrate solution for an equal time, he observed that the solution turned light green with the formation of a coating of silver metal on the strip. The correct conclusion of the student about the identity of metals X and Y is :
(1) X is copper and Y is magnesium
(2) X is zinc and Y is copper
(3) X is iron and Y is copper
(4) X is copper and Y is iron
