Question

How many hydrogen bonded water molecule $(s)$ are associated with $CuS{O}_4\cdot 5H_{2}O$ ?

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

Answer: (A)

The structure of complex $CuS{O}_4,5H_{2}O$ or $Cu(H_{2}O)S{O}_{4}4H_{2}O$ 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
