Question

What happens when a piece of aluminium metal is added to dilute hydrochloric acid ?

Answer 1

Aluminium reacts with dilute hydrochloric acid to give aluminum chloride and hydrogen gas.

The balanced equation is = 2Al(s) + 6HCl(aq) -----> 2AlCl3(aq) + 3H2(g).

Answer 2

When a piece of aluminium metal is added to dilute hydrochloric acid, the result is two products - an aqueous product and a gaseous product.

This can be explained by the equation below:

2Al + 6HCl -> 2AlCl3 + 3H2

Here,

AlCl3 is the aqueous product and H2 is the gaseous product.

This equation is an example of a single replacement reaction.
