HEY mate here is your answer.
hydrogen gas is evolved when an acid reacts with a metal.
it can be tested by putting fire over the test tube if there is any pop sound then it is not any one but hydrogen.
because hydrogen burns with a pop sound.
hope it helps you.

HEY FRIEND HERE IS UR ANSWER ,
When an acid react with a metal it liberates hydrogen gas.
E.g., Zn(s) + 2HCl(aq) ZnCl2 (aq) + H2(g)
To test the presence of H2 gas, bring a burning splinter near the mouth of the test tube where H2 gas is released, the match stick bums with a pop sound.
HOPE IT HELPS :)
