Even in solutions a gradual progression in the increase of the specific gravity shows itself, not only for equivalent solutions (for instance, RCl2 + 200H2O), but even with an equal percentage composition, as is seen from the curves giving the specific gravity (water 4° = 10,000) at 15° (for barium chloride, according to Bourdiakoff's determinations):
BeCl2: S = 9,992 + 67·21p + 0·111p2 CaCl2: S = 9,992 + 80·24p + 0·476p2 SrCl2: S = 9,992 + 85·57p + 0·733p2 BaCl2: S = 9,992 + 86·56p + 0·813p2
