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. Which of the following statement is true for the complex, [Co(NH_(3))_(4)Br_(2)]NO_(2)?

1.	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. Which of the following statement is true for the complex, [Co(NH_(3))_(4)Br_(2)]NO_(2)?
Answer» It shows IONISATION, linkage and geometrical isomerism. It does not show optical isomerism because its cis and trans forms each have at LEAST one plane of symmetry. Its ionisation isomers cannot be differentiated by SILVER nitrate solution. (a) and (B) both. Answer :D
