What is formation constant?

The formation constant is the equilibrium constant for forming a coordination complex, for example: Cu 2+ + 4NH 3 --> [Cu(NH 3) 4] 2+. the formation constant is the ratio of products to reactants for this.

Why is [Cu(NH3) 4] + a colourless complex?

Why is [Cu (NH3) 4] + a completely colourless complex, while [Cu (NH3) 4] 2+ gives intense blue colour in solution? The answer lies in the peculiarity of the arrangement of 3d and 4s electrons in transition elements.

What are the total possible coordination isomers of [Cu(NH3)4]?

The total possible coordination isomers for the following compounds respectively are: [Co (en)3] [Cr (C2O4)3] [Cu (NH3)4] [CuCl4] [Ni (en)3] [Co (NO2)6] . ]. ] has four possible coordination isomers. ]. ] has two possible coordination isomers. They are [Cu(NH 3 )].

What happens when HCL is added to [Cu(NH3)4]2+?

When conc. HCl is added to the solution containing [Cu (NH3)4]2+, Cl- ions will replace NH3 and form [Cu (Cl)4]2- complex. This can be understood for the following reaction: The Cl- ion is a weak field ligand, while NH3 is a strong field ligand. Hence, Cl- will in less splitting of d-orbitals, as compared to NH3.
