With copper turnings, hydrogen gas will not evolve because copper is less reactive, so, it does not react with dil. H 2 SO 4 of dil. HCl. Hence, no reaction will take place. Zinc also reacts with NaOH. So, if sodium hydroxide is taken, then hydrogen gas will be evolved. WebTo identify the gas given off by these reactions as hydrogen, it is necessary to test the gas: Collect the gas in a test tube. Put the flame from a burning splint into the top of the test tube. black oil in radiator
