How are transition metals formed from coloured salts?

Transition metals are often formed from colored salts through a process of chemical reactions, typically involving the reduction of metal ions. These salts, which contain transition metal ions, can be converted into their elemental forms by reducing agents such as hydrogen, carbon, or other metals. The characteristic colors of these salts arise from electronic transitions in the d-orbitals of the transition metal ions, which can change during the reduction process, leading to different colors or the formation of metallic solids. This process is widely utilized in inorganic chemistry and Metallurgy to extract and purify transition metals.
