Question

Write a test to identify this gas.observation

Answer 1

Answer:

H2(g)

Take the test tube con­tain­ing gas, hold­ing it up­side down, and bring a smol­der­ing can­dle lighter to the open end. If the test tube con­tained pure hy­dro­gen, with­out any oth­er mix­tures, there would be a loud noise re­sem­bling a whis­tle. How­ev­er, this will not hap­pen, as the gas mix­ture will con­tain air in any case. So when you con­duct this ex­per­i­ment, you will hear a loud pop. This sound will con­firm that you have ob­tained hy­dro­gen, and that the ex­per­i­ment was con­duct­ed cor­rect­ly.
