Obs. This solution is used as an antiseptic, disinfectant, and bleaching liquid.—Dose, 20 to 30 drops, in any bland fluid, in scarlet fever, sore throat, &c.; it is also made into a lotion, gargle, injection, and eye-water. Meat in a nearly putrid state, unfit for food, is immediately restored by washing or immersion in this liquid.
Solution of Chlo′′rine. Syn. Chlorine water; Solutio chlorinii, Liquor chlorini (Ph. L. & D.), Chlorinei aqua (Ph. E.), L. Prep. 1. (Ph. L.) On binoxide of manganese (in powder), 2 dr., placed in a retort, pour hydrochloric acid, 1 fl. oz., and pass the chlorine in distilled water, 1⁄2 pint, until it ceases to be evolved.
2. (Ph. E.) Muriate of soda (common salt), 60 gr.; red oxide of lead, 350 gr.; triturate them together, and put them into 8 fl. oz. of distilled water, contained in a stoppered bottle; then add of sulphuric acid, 2 fl. dr.; and having replaced the stopper, agitate the whole, occasionally, until the oxide of lead turns white; lastly, after subsidence, pour off the clear liquid into another stoppered bottle.
3. (Ph. D.) Introduce into a gas bottle peroxide of manganese (in fine powder), 1⁄2 oz.; add of hydrochloric acid, 3 fl. oz., (diluted with) water, 2 fl. oz.; apply a gentle heat, and cause the evolved gas to pass through water, 2 fl. oz., and then into a 3-pint bottle containing distilled water, 20 fl. oz., and whose mouth is loosely plugged with tow; when the air has been entirely displaced by the chlorine, cork the bottle loosely, and shake it until the chlorine is absorbed; it should now be transferred to a pint stoppered bottle, and preserved in a dark and cool place.
(B. P.) Liquor chlori. Prep. Put 1 oz. of black oxide of manganese, in fine powder, into a gas bottle, and having poured upon it 6 fl. oz. of hydrochloric acid, diluted with 2 oz. of distilled water, apply a gentle heat, and by suitable tubes cause the gas, as it is developed, to pass through 2 oz. of distilled water placed in an intermediate small phial, and thence to the bottom of a 3-pint bottle containing 30 oz. of distilled water, the mouth of which is loosely plugged with tow. As soon as the chlorine ceases to be developed, let the bottle be disconnected from the apparatus in which the gas has been generated, corked loosely, and shaken until the chlorine is absorbed. Lastly, introduce the solution into a green
bottle furnished with a well-fitting stopper, and keep it in a cool and dark place. Sp. gr. 1·003. One fluid ounce contains 2·66 grains of chlorine.
Prop., &c. Irritant and acrid, but, when largely diluted, stimulant and antiseptic.—Dose, 1⁄2 to 2 fl. dr., in 1⁄2 pint of water, sweetened with a little sugar, in divided doses, during the day; in scarlatina, malignant sore throat, &c. On the large scale, liquid chlorine may be procured by passing the gas obtained by any of the methods named under Chlorine into water, until it will absorb no more.
Solution of Cit′rate of Ammo′′nia. Syn. Liquor ammoniæ citratis (B. P., Ph. L.), L. Prep. (Ph. L.) Dissolve citric acid, 3 oz., in distilled water, 1 pint; and to the solution add of sesquicarbonate of ammonia (in powder), 21⁄2 oz., or q. s. to exactly neutralise the liquor.—Dose, 2 to 6 fl. dr.
Solution of Citrate of Magne′sia. Syn. Solution magnesiæ citratis. See Magnesium, Citrate of.
(B. P.) Carbonate of magnesia, 100 gr.; citric acid, 200 gr.; syrup of lemons, 1⁄2 fl. oz.; bicarbonate of potash in crystals, 40 gr.; water, q. s. Dissolve the citric acid in 2 oz. of the water, and having added the carbonate of magnesia, stir until it is dissolved. Filter the solution into a strong half-pint bottle, add the syrup and water sufficient to nearly fill the bottle, then introduce the bicarbonate of potash, and immediately close the bottle with a cork, which should be secured with string or wire, afterwards shake till the bicarbonate has dissolved.—Dose, 5 to 10 fl. oz.
