Q. How many hydrogen bonded water molecule $ (s) $ are associated with $ CuSO_4 \cdot 5H_2O $ ?

AMUAMU 2010Coordination Compounds

Solution:

The structure of complex $CuSO_{4}, 5H_{2}O$ or $Cu(H_{2}O)SO_{4} 4H_{2}O$ is as
In crystalline form, four water molecules are coordinated with $Cu$ atom forming a square-planar geometry and the two $O$ atoms of sulphate ion complete the distorted octahedron. The fifth water molecule is attached through $H$-bonding between one of the coordinated $H_{2}O$ molecule and one of the sulphate ion
