Question

Gas released when acid reacts with aluminium

Answer 1

Answer:

Hydrogen gas

Explanation:

When any metal (which is more reactive than hydrogen) reacts with an acid, hydrogen gas is released.

For eg: Let's assume the acid is Hydrochloric Acid here.

Then, $2Al + 6HCl --> 2AlCl_{3} + 3H_{2}$

As we can see Hydrogen gas is being formed and released here.
