$4$ and $1$

Vedclass · Answer

(B) In the structure of $CuSO_{4} \cdot 5H_{2}O,$ the copper ion $(Cu^{2+})$ is coordinated to $4$ water molecules directly,which defines its secondary valency as $4$.The fifth water molecule is not directly coordinated to the $Cu^{2+}$ ion but is held in the crystal lattice by hydrogen bonding between the water molecule and the sulfate $(SO_{4}^{2-})$ group.Therefore,the secondary valency is $4$ and the number of hydrogen-bonded water molecules is $1$.

The secondary valency and the number of hydrogen bonded water molecule$(s)$ in $CuSO_{4} \cdot 5H_{2}O,$ respectively,are :
