The purpose of the research was to study the formation and combustion of acetylene. The percent yield of the reaction of calcium carbide and a proton donor, water, to form acetylene and calcium oxide was first determined by measuring the volume of evolved acetylene in a eudiometer. On average, the calcium carbide produced a 67% yield of acetylene. The theoretical volume of acetylene to fill a 9 in. diameter balloon was then calculated, and the required amount of calcium carbide was found to be 23 g. A technique was developed to capture the generated acetylene gas. When a lit splint was put to the acetylene-filled balloon, under controlled conditions, it quickly combusted and produced a bright flame.
