Hygroscopy:
When certain substances are exposed to at room temperature, they absorb moisture without changing their .
These substances are known as substances, and this property is known as hygroscopy. As , hygroscopic substances are used.
They may be solids or liquids. When exposed to air, hygroscopic substances do not change their .
For example, concentrated sulphuric acid (\(H_2SO_4\)), phosphorous pentoxide (\(P_2O_5\)), quick lime (\(CaO\)), silica gel (\(SiO_2\)).
Deliquescence:
When exposed to the at ordinary temperatures, certain substances that are so hygroscopic absorb enough and get completely dissolved.
Such substances are called substances, and this property is called deliquescence.
When deliquescent substances are exposed to air, their changes. They are crystalline solids.
For example, caustic soda (\(NaOH\)), Caustic potash (\(KOH\)) and Ferric chloride (\(FeCl_3\)) etc.
