Preparing Acetylene
Water is dripped slowly from a dropping funnel onto the calcium carbide in a flask, and the gas is collected over water in gas jars. The reaction, CaC2 + 2H2O → C2H2 + Ca(OH)2, needs no heating, and the residue left in the flask is calcium hydroxide.
Tests on the Gas
Acetylene decolourises bromine water as bromine adds across its triple bond. With Tollens’ reagent it gives a white precipitate of silver acetylide, and with ammoniacal copper(I) chloride a red-brown one of copper(I) acetylide, tests that identify a terminal alkyne.
