Problem

A six coordinate complex of formula

\text{CrCl}_3 \cdot 6\text{H}_2\text{O}

has green colour. A 0.1 M solution of the complex when treated with excess of

\text{AgNO}_3

gave 28.7g of white precipitate. The formula of the complex would be : (1)

[\text{Cr}(\text{H}_2\text{O})_6]\text{Cl}_3

(2)

[\text{CrCl}(\text{H}_2\text{O})_5]\text{Cl}_2 \cdot \text{H}_2\text{O}

(3)

[\text{CrCl}_2(\text{H}_2\text{O})_4]\text{Cl} \cdot 2\text{H}_2\text{O}

(4)

[\text{Cr}(\text{H}_2\text{O})_3\text{Cl}_3]
