Question
Differentiate hydrate and anhydrous salts with examples.
Solution
| Property | Hydrate Salts | Anhydrous Salt |
| Definition | Salts that contain water molecules as part of their crystal structure. | Salts that do not contain water molecules in their structure. |
| Water Content | Contain a fixed number of water molecules (water of crystallization). | Do not contain any water molecules. |
| Appearance | Often appear colored and crystalline. | Usually powdery and may appear white or dull. |
| Example | Copper sulphate pentahydrate (\[\ce{CuSO4.5H2O}\]) | Heating of Copper sulphate pentahydrate (\[\ce{CuSO4.5H2O}\]) produce anhydrous copper sulphate (\[\ce{CuSO4}\]) |
