${\green{\dashrightarrow}}$Hydrogen gas is usually liberated when an acid reacts with a metal.

When zinc granules react with dilute sulphuric acid, then the bubbles of the soap solution are formed. These soap bubbles contain hydrogen gas and zinc sulphate solution is formed.

Zn +2 H_2SO_4\Rightarrow Zn(SO_4)_2+2H_2

The evolved hydrogen gas can be tested by taking a burning candle near soap solution containing hudrogen gas . If candle burns with pop sound, it confirms the evolution of hydrogen gas.
