The charge on the complex ion in K₂[PtCl₄] is +2

The coordination number of Hg in [Hg(en)₂]²⁺ is 4

The oxidation number of Fe in [Fe(CN)₆]⁴⁻ is +6

In transition metal complexes, ligands act as Lewis acid

Less availability of Ag⁺ ions, as Cu cannot displace Ag from [Ag(CN)₂] ion

More voltage is required

A thin layer of Ag is formed on Cu

Ag⁺ ions are completely removed from solution

These molecules have non super imposable mirror images

These molecules posses a center of symmetry

These molecules possess a plane of symmetry and hence, are achiral

These molecules possess C_n axis of symmetry

In K₃[Fe(CN)₆], the ligand has satisfied both primary and secondary valencies of ferric ion

In K₃[Fe(CN)₆], the ligand has satisfied only the secondary valency of ferric ion

In K₄[Fe(CN)₆], the ligand has satisfied both primary and secondary valencies of ferrous ion

In [Cu(NH₃)₄]SO₄, the ligand has satisfied only the secondary valency of copper
