Double salts are addition compounds which lose their identify in aqueous solution whereas complexes which are also addition compounds do not lose their identify in aqueous solution. The coordination compounds show isomerism and find application in photography , qualitative analysis, metallurgy, water purification and in the treatment of various diseases. Choose the correct option for the complex [Pt Cl_(2)(en)_(2)]^(2+).
