Explanation:
Hydrates are compounds in which a specific number of water molecules are associated with each formula unit of a crystalline substance. These water molecules are called water of crystallization. When a hydrate is heated, the water molecules are released as water vapor, leaving an anhydrous compound behind.
Among the given options, sodium chloride (NaCl) does not exist as a hydrate. NaCl is an ionic compound, and it does not have any water of crystallization associated with it. Hence, it is an anhydrous compound.
Let's see the other options one by one:
Ferrous sulphate: FeSO4.7H2O (heptahydrate)
Magnesium sulphate: MgSO4.7H2O (heptahydrate)
Copper sulphate: CuSO4.5H2O (pentahydrate)
All these compounds have a specific number of water molecules associated with each formula unit of the compound. Hence, they exist in the hydrate form.
Conclusion:
Sodium chloride does not exist as a hydrate because it is an ionic compound and does not have any water of crystallization associated with it.

Baking soda, or sodium bicarbonate (NaHCO3), is a chemical that can undergo a decomposition reaction when heated. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2)
