Note 41 — Chapter X · SODIUM CHLORIDE—BERTHOLLET'S LAWS—HYDROCHLORIC ACID
George Kamensky translation
The figures cited above may serve for the direct determination of that variation of the specific gravity of solutions of hydrochloric acid with the temperature. Thus, knowing that at 15° the specific gravity of a 10 p.c. solution of hydrochloric acid = 10,492, we find that at t° it = 10,530 - t(2·13 + 0·027t). Whence also may be found the coefficient of expansion (Note 40).
