KnowledgeBoat · Accepted Answer

(a) Laboratory preparation of methane A mixture of sodium ethanoate (sodium acetate) and soda lime is taken in a hard glass test tube and heated over a bunsen flame.  The gas evolved is collected by downward displacement of water since it is slightly soluble in water and is lighter than air. (b) Laboratory preparation of ethane A mixture of sodium propionate and soda lime is taken in a boiling tube and heated over a bunsen flame.  The gas evolved is collected by downward displacement of water.
