Strong Sulphuric Acid.—Spec, grav., ; containing per cent, anhydrous sulphuric acid. Obtained by care-fully mixing, in a flask or beaker, 1 part of water with 3 partsof concentrated sulphuric acid (Fig. 4). In diluting concentratedsulphuric acid with water, theacid should invariably andgradually be added to thewater, and in vessels whichare either placed in cold water,or which are not liable to crackfrom the heat evolved. Diluted Sulphuric Acid. —Spec, grav., ; con-taining about per cent,of anhydrous sulphuric by mixing 1 partof concentrated sulphuric acidwith 5 parts of water. Sulphurous Acid.—An aque-ous solution of sulphurous-acid gas, saturated at 15 C, con-taining about 37 times its volume of gas.
