Question

In solid $CuS{O}_4.5H_{2}O$ ,copper is coordinated to number of water molecule:-

• A. 5
• B. 4
• C. 1
• D. 2

Answer 1

The correct option is B 4

We know that, $CuS{O}_4.5H_{2}O$ can also be written as $\left[Cu(H_{2}O{)}_4\right]S{O}_4.H_{2}O$. Here, the four water molecules inside the coordination sphere are coordinated to Cu and the one water molecule which is outside the coordination sphere is hydrogen bonded.

Hence,(b) is the correct answer.
