Note 32 — Chapter XII · SODIUM
George Kamensky translation
The specific gravity of solutions of sodium hydroxide at 15°/4° is given in the short table below:—
NaHO, p.c. 5 10 15 20 30 40
Sp. gr. 1·057 1·113 1·169 1·224 1·331 1·436
1,000 grams of a 5 p.c. solution occupies a volume of 946 c.c.; that is, less than the water serving to make the solution (see Note 18).
