of the complex [Ni(NH3)5Br]Cl] the ionization isomer will give colour with AgNO3......
1.yellow
2.blue
3.white
4.red

Please explain the right with detailed explanation

Dear Student

The correct option is (a) because -
[Ni(NH_​3)₅Br]Cl when treated with AgNO₃ solution gives rise to the following ions -
[Ni(NH_​3)₅Cl]⁺ + Br^-

This Br^- combines with Ag⁺ ions to form AgBr (silver bromide, a pale-yellow precipitate).
Ag⁺ + Br^- ---> AgBr
