3. Liquor calcis chloratæ (B. P.). Prep. Blend well together, by trituration in a large
mortar, 1 lb. of chlorinated lime with 1 gall. of water, transfer the mixture to a stoppered bottle, and shake it frequently for the space of 3 hours; pour it on a calico filter, and let the solution which passes through be kept in a well-stoppered bottle. Sp. gr. 1·035.
Obs. The last is the usual strength sold in trade, under various attractive names, to give it importance. It is used as a disinfectant, bleacher, and fumigation; and, diluted with water, as a lotion, injection, or collyrium, in several diseases. See Hypochlorite of Calcium.
Solution of Chlorinated lime, Spirituous. Syn. Solutio calcis chloridi, spirituosa. (Chevallier). Prep. Chloride of lime, 3 dr.; distilled water, 2 oz.; rectified spirit, 2 oz. Mix and filter.
Solution of Chlorinated Potas′sa. Syn. Solution of chloride of potash‡, S. of hypochlorite of potassa, Javelle’s bleaching liquid; Solutio potassæ hypochloris, Liquor potassæ chloridi, L. potassæ chlorinatæ, L.; Eau de Javelle, Fr. Prep. 1. Dissolve carbonate of potassa, 1 part, in water, 10 parts, and pass chlorine gas through the solution to saturation.
2. Chloride of lime (dry and good), 1 part; water, 15 parts: agitate them together for an hour; next dissolve of carbonate of potassa, 2 oz., in water, 1⁄4 pint; mix the two solutions, and after a time either decant or filter.—Uses, &c. As the last.
Solution of Chlorinated Soda. Syn. Solution of chloride of soda‡, S. of hypochlorite of soda, Labarraque’s disinfecting liquid; Solutio sodæ hypochloris, Hypochloris sodicus aqua solutus (P. Cod.), Liquor sodæ chlorinatæ (Ph. L. & D.), L. Prep. 1. (Ph. L.), Carbonate of soda (in crystals), 1 lb.; water, 1 quart; dissolve, and pass through the solution the chlorine evolved from a mixture of common salt, 4 oz.; binoxide of manganese, 3 oz.; sulphuric acid, 21⁄2 fl. oz. (4 oz.—Ph. L. 1836); diluted with water, 3 fl. oz.; placed in a retort, heat being applied to promote the action, and the gas being purified by passing through 5 fl. oz. of water before it enters the alkaline solution.
2. (Ph. D.) Chlorinated lime, 1⁄2 lb., and water, 3 pints, are triturated together in a marble mortar, after which the mixture is transferred to a stoppered bottle, agitated frequently during three hours, and then filtered through calico; in the mean time carbonate of soda (cryst.), 7 oz., is dissolved in water, 1 pint; the two solutions are next mixed, and, after agitation for about 10 minutes, the whole is filtered as before. The filtrate is to be preserved in a well-stopped bottle.
3. (B. P.) Dissolve 12 oz. of carbonate of soda in 36 oz. of distilled water, and put the solution into a glass vessel. Mix black oxide of manganese, 4 oz., and hydrochloric acid, 15 fl. oz., in a glass flask, with a bent tube
attached by means of a cork to its mouth, apply a gentle heat, and with a suitable arrangement cause the gas evolved to pass first through a wash-bottle containing 4 oz. of water, and then into the solution of carbonate of soda, regulating heat so that the gas shall be slowly but constantly introduced. When the disengagement of chlorine has ceased, transfer the solution which has absorbed it to a stoppered bottle, and keep in a cool and dark place. Sp. gr. 1·103.
