Chemistry - Hydrogen and Its compound Question with Solution | TestHub

${\mathrm{BaCl}}_2\cdot 2{\mathrm{H}}_2\mathrm{O}$ : interstitial water

$\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]{\mathrm{Cl}}_3$ : co-ordinated water

$${\mathrm{CuSO}}_4\cdot 5{\mathrm{H}}_2\mathrm{O}\Rightarrow [\mathrm{Cu}\underset{\begin{array}{c}\text{ co-ordinated }\text{ water }\end{array}}{\underbrace{{\left({\mathrm{H}}_2\mathrm{O}\right)}_4}}{]}^{2+}{\mathrm{SO}}_4^{2-}\cdot \underset{\text{H-bonded water }}{\underbrace{{\mathrm{H}}_2\mathrm{O}}}$$
