Some gases are hard to distinguish by sight or smell alone. For example, hydrogen, oxygen and nitrogen are all colourless and odourless. Several laboratory experiments are capable of producing relatively pure gas as an end product, and it may be useful to demonstrate the chemical identity of that gas. Burning splints or glowing splints can be used to identify whether a gas is flammable, whether it is oxidising, or whether it is chemically inert. WebExplain that pure hydrogen – rather than a mixture of hydrogen and air – is being tested if the test tube was full of gas before it was removed. For the oxygen test, care should be taken that the dampness at the mouth of the test tube does not extinguish the ‘glow’, causing the test to fail. portland maine dating
