Hydrogen (Oxford AQA IGCSE Chemistry)

Test for Hydrogen Gas

• The test for hydrogen consists of holding a burning splint at the open end of a test tube of gas

• If the gas is hydrogen it burns with a loud “squeaky pop” which is the result of the rapid combustion of hydrogen with oxygen to produce water

• Be sure not to insert the splint right into the tube, just at the mouth, as the gas needs air to burn
