The two products are separated by the different solubilities of their sulphates.
1902), under Ramsay's direction, for comparing solubilities which are in many respects analogous to vapour-pressures.
The best source of rubidium salts is the residue left after extracting lithium salts from lepidolite, the method of separation being based on the different solubilities of the platino-chlorides of potassium, rubidium and caesium in water (R.
A somewhat similar process based on the varying solubilities of the corresponding alums has also been devised by Redtenbacher (Jour.
