Testing for Hydrogen Gas
Aim To show that hydrogen gas is produced when a metal reacts with acid.
Equipment Two test tube,wooden splint,Safety glasses and lighter
Method
add your sample of metal to your test tube add 2 ml of acid
Carefully invert the boiling tube above the test tube containing the metal and acid
Hold the test tubes together for a few minutes allowing time for the inverted boiling tube to fill with gas
When you think the tube is full your lab partner should light a wooden splint
Carefully but quickly tilt the boiling tube of gas upwards and insert the burning splint into the mouth of the test tube
Observations When we put the burning splint into the boiling tube the flame made the gas come out with a popping sound
