The secondary valency and the number of hydrogen bonded water molecule(s) in CuSO4 . 5H2O, respectively, are :
Solution
CuSO<sub>4</sub>.5H<sub>2</sub>O $\Rightarrow$ [Cu(H<sub>2</sub>O)<sub>4</sub>]SO<sub>4</sub>.H<sub>2</sub>O<br><br>
In CuSO<sub>4</sub>.5H<sub>2</sub>O, Cu is co-ordinated with 4 water molecule and two more oxygen atom from sulphate ion and fifth water molecule is hydrogen bonded.<br><br>
So secondary valency = 4<br><br>
No. of hydrogen bond per molecule = 1
