The names of the following are as follows:
(i) Copper (II) Sulfate Pentahydrate (CuSO4.5H2O).
(ii) Anhydrous Magnesium (II) Sulphate.
(iii) Honey
- Efflorescence is the spontaneous removal of water of crystallization of a hydrated salt to form an anhydrous salt.
- Copper (II) Sulfate Pentahydrate is a crystalline solid that is blue in colour and when exposed to air, it loses its water of crystallization from its surface to form a white layer of anhydrous copper (II) sulfate.
- Anhydrous Magnesium Sulphate is a white crystalline solid that does not contain any water of crystallization and hence it is anhydrous.
- Hygroscopic substance attracts water to its surface from the surrounding environment and Honey is one such liquid.
