Interpretation Introduction

Interpretation:

When $\text{3}\text{.10g}$ of anhydrous ${\text{NiSO}}_{\text{4}}$ exposed to moist air, to forms $\text{5}\text{.62g}$ of hydrate ${\text{NiSO}}_{\text{4}}$ then the formula of this hydrate has to be identified.

Concept Introduction:

Hydrates:

A solid compound contains water molecule called hydrates.  For example ${\text{AlCl}}_{\text{3}}{\text{•6H}}_{\text{2}}\text{O}$, this indicates six molecules of water are attached to aluminium metal ion.

Anhydrase:

A substance contains no water molecule.
