Ammonium hexachlorostannate is the ammonium salt of hexachlorotin (IV) acid H 2 [SnCl 6 ].
Extraction and presentation
Ammonium hexachlorostannate is formed from tin (IV) chloride (stannous chloride ) and ammonium chloride (salmiac).
properties
Ammonium hexachlorostannate is a white solid that is soluble in water.
The compound crystallizes cubic , space group Fm 3 m (space group no. 225) , with the lattice parameter a = 10.04 Å .
use
Due to its use for dyeing (as a stain ), it is also referred to by the technical name of pink salt ( pink = pink). The neutral reacting salt is used where the tin (IV) chloride solution containing free acid cannot be used.
It accelerates the development of the tin plague .
