Answer: Hydrogen gas is liberated when an acid reacts with a metal .For example , when zinc metal reacts with dil . HCl , hydrogen is evolved and salt , zinc chloride is formed as : Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
It can be tested by bringing a burning candle near the gas . The candle continues burning with a pop sound.
