hit the nail on the head!
hydrogen - sqeaky pop
oxygen - relight glowing splint
co2 - turns limewater cloudy
chlorine - bleaches damp litmus paper
water - test by boiling point, using white anhydrous copper sulphate which turns blue with water, or anhydrous cobalt chloride paper goes from blue to pink..
