Which of the following isomers will give white precipitate with

BaC{l}_{2}

solution?

Options

A $[ Co ( N{H}_{3}{)}_{5}S{O}_{4} ] Br$
B $[ Co ( N{H}_{3}{)}_{5}Br ] S{O}_{4}$
C $[ Co ( N{H}_{3}{)}_{4} ( S{O}_{4}{)}_{2} ] Br$
D $[ Co ( N{H}_{3}{)}_{4}Br ( S{O}_{4} ) ]$

Correct answer

B. $[ Co ( N{H}_{3}{)}_{5}Br ] S{O}_{4}$

Step-by-step solution

White precipitate is due to formation of barium sulphate.

[ Co ( N{H}_{3}{)}_{5}Br ] S{O}_{4} ⇌ [ Co ( N{H}_{3}{)}_{5}Br{]}^{2 +} + S{O}_{4}^{2 -}

{\text{SO}}_{4}^{\text{2} -} \text{+}{\text{BaCl}}_{2} \to \mathop{{\text{BaSO}}_{4}}_{\text{white}\text{ppt}} \text{+}{\text{2Cl}}^{−}
