Question

The composition of carnalite is

Answer 1

Carnallite’s chemical formula is KMgCl3·6(H2O).

Synthetic carnallite crystal specimens can be produced from 1.5 mole percent KCl and 98.5 mole percent MgCl2·6H2O by slow crystallization at 25°C.

Its density is 1.602 g/cm3.

Carnallite can also be produced by grinding the combination of hydrated magnesium chloride and potassium chloride.

Answer 2
