ITENDYFYING THE HYDROGEN GAS

Observe the colour and odour of a hydrogen sample you collected.
                      Close one boiling tube filled with hydrogen with a glass plate and hold its mouth upwards. Then insert a lighted taber into it as you open the lid.
                        The gas burns with a ‘pop’ sound. This shows that hydrogen is an in flammable gas.
