Question

What happens when zinc reacts with hydrochloric acid?

Answer 1

Zn+HCL⇒H₂+ZnCl₂
It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt.Zinc reacts quickly with the acid to form bubbles of hydrogen. 

Answer 2

Given that,

Zinc and hydrochloric acid.

To find,

The reaction of zinc and hydrochloric acid.

Solution,

Zinc is a metal and hydrochloric acid is an acid. When an acid reacts with metal, salt is formed with the evolution of hydrogen gas.

Zinc is Zn

Hydrochloric acid is HCl

The reaction is as follows :

$Zn+HCl\rightarrow ZnCl_2+H_2$

Balancing the above equation,

$Zn+2HCl\rightarrow ZnCl_2+H_2$

ZnCl₂ is zinc chloride

Hence, when zinc reacts with hydrochloric acid, zinc chloride is formed with the evolution of hydrogen gas.
