By precipitating a solution of manganous sulphate with a solution of sodium phosphate.
In the more chronic cases the persistent use of sodium phosphate is to be highly commended.
A cure may be confidently looked for in this malady by the persistent use of sodium phosphate—drachm j ter in die.
A white powder obtained by precipitating ferric chloride by sodium phosphate.
The magnesia is precipitated from the filtrate by the addition of an excess of sodium phosphate and ammonia.
Sodium sulphate and sodium phosphate crystals lose water even when exposed under ordinary conditions to dry air.
The filtrate is treated with sodium phosphate, and the magnesia is weighed as pyrophosphate, or titrated with uranium acetate.
Titrate the boiling solution with the sodium phosphate till it ceases to give a brown colouration with potassium ferrocyanide.
Polymorphism was first observed by Mitscherlich in the case of sodium phosphate, and later in the case of sulphur.
Cupric phosphate, Cu3(PO4)2, may be obtained by precipitating a copper solution with sodium phosphate.
