3884. Gregory's Method of Obtaining Pure Muriatic Acid

3884. Gregory's Method of Obtaining Pure Muriatic Acid. Put into a matrass 6 parts, by weight, of purified salt, and 10 ounces oil of vitriol previously diluted with. 4 of water, and cooled. Fix in the matrass a tube twice bent at right angles and having a bulb blown on the descending limb. Into a bottle surrounded with ice and water introduce distilled water equal in weight to the salt employed, and let the bent tube dip1/8 of an inch into the water. Apply a gentle heat of a sand-bath to the matrass as long as acid comes over. In about 2 hours the operation will be finished. The water is increased 2/3 in bulk, and converted into hydrochloric acid of 1.14 or 1.15 specific gravity. To procure it of 1.21 specific gravity, employ part of this acid during the first half of a similar operation, and it will be speedily saturated. Phillips says a perfectly colorless acid may be obtained from the commercial sulphuric acid and common salt.

3885. Dilute Muriatic Acid

3885. Dilute Muriatic Acid. Mix 4 troy ounces muriatic acid with sufficient distilled water to make a pint. The specific gravity of the diluted acid is 1.038. (U. S. Ph.)
