Question

Define hygroscopic , efflorescence , deliquenscene

Answer 1

Hygroscopic refers to a matter's ability to adsorb and absorb water from the surrounding environment.

Efflorescence is the spontaneous loss of water by a hydrated salt, which occurs when the aqueous vapor pressure of the hydrate is greater than the partial pressure of the water vapour in the air

Deliquescence is the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution.
