Question

Alloy of zinc and cu dissolved in dilute hcl.Hydrogen gas os evolved ?

Answer 1

Answer:

Zinc reacts with dilute HCl

Explanation:

In the electrochemical series, the elements are listed according to their decreasing reactivity.

Copper (Cu) lies below Hydrogen and therefore it cannot reacts with Hydrogen while Zinc (Zn) lies above the Hydrogen in the table and thus it reacts with HCl to liberate the Hydrogen gas.
