How will you test whether the gas evolved in a reaction is hydrogen?
(N/A) To test for hydrogen gas,bring a burning matchstick or a burning splinter near the mouth of the test tube from which the gas is being evolved.
If the gas is hydrogen,it will burn with a characteristic '$pop$' sound,which is caused by the rapid combustion of hydrogen in the presence of oxygen.
