The complex `[Co(NH_3)_5Br] SO_4` give white precipitates with `BaCl_2` solution while `[CO(NH_3)_5SO_4]Br` give yellow precipitate with `AgNO_3` solution. Explain.

The complex [Co(NH_3)_5Br]SO_4 will give white precipitates with

Iodoform gives a precipitate with AgNO_3 . Why ?

An aqueous solution of [Pt(NH_3)_2Cl_2] gives white precipitate of AgCl with AgNO_3(aq) .

An aqueous solution of [Pt(NH_3)_2Cl_2] gives white precipitate of AgCl with AgNO_3(aq) .

The solution of the complex [Cu(NH_3)_4]SO_4 in water will

A metal complex having the molecular formula Cr(NH_3)_4Cl_2 ,Br have been isolated in two forms (A) and (B). The form (A) reacts with AgNO_3 giving white precipitate readily soluble in dilute NH_4OH while (B) gives a yellow precipitate soluble in concentrated NH_4OH . Answer the following questions : The formula of complex A is
