PHOSPHATES PHOSPHATES for the soda fountain are a solution of acid phosphate with any of the fruit or flavored syrups, omitting the soda foam, as phosphates are served solid. To each gallon of flavored syrup 8 fl.oz. of acid phosphate is added. 1. — Bone ash, 32 av.oz.; sulphuric acid, 24 av.oz.; water, sufficient to make 1 gal. Mix the bone ash with 2 pt. of water in a glass or earthenware or other container which is not acted upon by the acid; add the acid previ- ously diluted with the remainder of the water and mix thoroughly. Set the mixture aside for 24 hours with occa- sional stirring, then transfer the same upon a strong muslin strainer and subject to pressure, avoiding contact with metals; add to the magma some water and let drain until 1 gal. of liquid has been obtained, then filter through paper. 2. — Phosphoric acid, 50 per cent., 64 parts; precipitated chalk, 12 parts; calcined magnesia, 1 part; potassium carbonate, 1 part; distilled water, 178 parts. Add the chalk to the acid gradually and then add the magnesia and stir well. Dissolve the potassium carbonate in 9 fl.oz. of the water, add the solution gradually to the acid liquor, admix the remainder of the water, set aside for 1 or 2 hours and filter. 3. — Phosphoric acid, 8 oz.; potassium phosphate, 80 100 Acid Phosphates
