tetramminosulphate, and when the liquid is boiled, and the product dissolved in
water, [Pt(NH3)4(OH)(N03)](N03)2, is formed. The tetramminosulphate is insoluble
in alcohol. P. T. Cleve reported platinous triamminosulphate, Pt(NH3)3S04,
to be formed by treating the corresponding chloroplatinite with silver sulphate,
evaporating the filtrate, and drying the snow-white mass of crystals at 100°.
E. Rosenbohm studied the magnetic susceptibility. The salt is sparingly soluble
in cold water, but readily soluble in hot water. L. A. Tschugaeff and I. Tscherniaeff
prepared platinous octammino-diol-sulphate, [(NHg)4Pt^(OH)2---Pt(NHa)4]SO4, as
indicated in connection with the aquotriammines. R. Uhlenhuth prepared triclinic
crystals of platinoustetrahydroxylaminosulpliate,Pt(NH2OH)4SO4. "L. A. Tschugaeff
and M. S. GrigoriefiE prepared platinous tetrahydrazinosulphate, [Pt(N2H^)4]SO4.
J. Reiset, P. T. Cleve, and L. Ramberg prepared platinous trans-sulphatodiammine,
[Pt(NH3)2(S04)].H20, by boiling the corresponding iodide or the
chloride with silver sulphate, and evaporating the clear liquor. The air-dried salt
does not lose water at 120°, but at higher temp, water is lost in the decomposition.
The salt is sparingly soluble in cold water, but more soluble in hot water. The
aq. soln. reacts acidic. Soluble chlorides precipitate from the aq. soln. the dichlorodiammine
; aqua regia forms platinic Z'ran&'-tetrachlorodiamrnine ; iodine tincture
forms platinic tetraiododiammine ; and aq. ammonia forms platinous tetramminosulphate.
P. T. Cleve obtained the corresponding platinous cis-sulphatodiammine,
from the corresponding cis-dichlorodiammine.

JL. N. Vauquelin obtained a dark green precipitate by evaporating a mixed
soln. of platinous and potassium sulphates. The dried mass is black and probably
represents an impure potassium sulphatoplatinite. At a red heat, it leaves a
residue of platinum and potassium sulphate.
E. Prost reported a subsulphide, ammonium subsulphatoplatinite, 2(NH4J2SO4.
Pt8(S04)2.25H2O, to be formed by adding alcohol to a mixed soln. of ammonium
and platinum subsulphate.
