Gas tests - Chemistry

what test would you use to test for hydrogen

The pop test, where a lit splint produces a "pop" sound when it ignites hydrogen gas.

what test would you use to test for carbonates

The limewater test, where carbon dioxide reacts with calcium hydroxide to produce a milky solution.

what test would you use to test for sulfates

The barium chloride test, which produces a white precipitate of barium sulfate when sulfate ions are present.

what test would you use to test for oxygen

The oxygen gas test is a method used to confirm the presence of oxygen by observing if a glowing splint reignites when placed in a sample of gas. This indicates a high concentration of oxygen in the sample.

what test would you use to test for carbon dioxide

The carbon dioxide test involves bubbling the gas through limewater, which turns milky in the presence of carbon dioxide due to the formation of calcium carbonate.

what test would you use to test for chlorine

The chlorine gas test is performed by using damp litmus paper, which turns white when exposed to chlorine due to the bleaching effect of the gas.
