Preparation of barium chloride

Preparation of barium chloride

170 ml of concentrated hydrochloric acid is diluted with 430 ml of water and poured in a porcelain evaporating dish. The solid barium carbonate in small portions is added and stirred after. If the barium carbonate is added too rapidly the mixture will froth out of the dish. After all the barium carbonate has been added and the solution becomes neutral to litmus the mixture is heated to boiling. If barium carbonate contains iron as impurity it could be removed by adding 3 g of barium peroxide and boiling gently the solution for 5 minutes. The hot solution of barium chloride is diluted to 600 ml and filter (while hot) without suction into a 600 ml beaker, keeping both the funnel and the beaker covered to prevent the solution from cooling and crystallizing prematurely. To the filtrate, 10 ml of dilute hydrochloric acid is added to maintained the acidic medium. Then the solution is poured into the crystallizing dish and allowed to stand uncovered until a satisfactory crop of crystals is obtained. Barium chloride has a tendency to “creep”, to prevent this it is advisable to grease the rim of the crystallizing dish. The obtained crystals are decanted and wash with a little amount of distilled water. Finally, barium chloride is dried thoroughly at room temperature or in the desiccator.
