Gas , 4 glass cylinders with flat-ground glass lids, hot plate
Aluminum carbide (F), NaOH (c = 0.05 mol / l) (Xi).
Put some aluminum carbide in the flask; the dropping funnel is filled with the dilute sodium hydroxide solution. Little by little sodium hydroxide solution is added to the carbide from the dropping funnel. Then it is heated to boiling. The resulting gas is collected in the 4 cylinders.
Aluminium carbide (Al4C3) reacts with water to form methane (CH4). The chemical reaction can be written as:
Al4C3 + 12 H2O → 4 Al(OH)3 +3 CH4
