A six coordinate complex of formula CrCl3.6H2O has green colour. A 0.1 M solution of the complex when treated with excess of AgNO3 gave 28.7 g of white precipitate. What would be the formula of the complex?
Answer & explanation
Correct answer: option 2
Since 0.1M complex gives 0.2 mole AgCl means 2Cl− are ionisable or out of coordination sphere so, complex is [Cr(H2O)5Cl]Cl2.H2O
