An introduction to practical chemistry : including analysis . A C I D I M E T It Y, 81 soluble nitrate of lime (CaO,NO^) has been washed out,and that nothing remains but the portion of marble. which was not decomposed. This residue must nowbe thoroughly dried, weighed, and its weight deductedfrom that of the whole of the marble employed ; thedifference being of course the weight of that which hasbeen dissolved by the acid. Now since every equiva-lent of carbonate of lime which has been dissolved,indicates the presence of an equivalent of nitric acid,the quantity of nitric acid in the 100 grains employedmay be ascertained by the following proportion: Atomic weight of Atomic weight ofcarbonate of lime. nitric acid. 50 54 ( Quantity of mar-1I ble dissolved J Percentage of nt. acid. 170. Ascertain the percentage of hydrochloric acid(HCi) in a specimen of the liquid acid. Proceed, exactlyas in the previous experiment with nitric acid (168),^only in the calculation substitute the atomic weight ofhydrochloric acid 37, for that of nitric, thus: 50 37 Quantity of marble dissolved : x 82 ACIDIMETIIY. 171. In the determination of the strength of acidswhich do not form with lime salts
