In nitroprusside ion, the iron and NO exists as Fe(II) and rather than Fe(III) and NO. This can be established by
Measuring the solid state magnetic moment
Fe(II) state – 3d6 ; due to strong CN– ligand spin paired complex (d2sp3) will be formed.
Hence n = 0, μ = 0 B.M
Fe(III) state 3d5;d2sp3 complex, n = 1, μ = 1.73 B.M.
When HgI2 is added to excess of aqueous KI, mercury largely exists as
The solution of AgBr in presence of large excess of NH3 contains mainly the cation

Follow the order
On treatment of 100 ml of 0.1 M solution of the complex CrCl3.6H2O with excess of AgNO3.4.305g of AgCl was obtained. The complex is
