Answer:

hope it helps!

Explanation:

Deliquescent substances - certain solid substances, when exposed to air absorb water, enough to form solutions. Example, solid NaOH, CaCl2, CaCl2. 6H2O, P4O10 (forms HPO3), FeCl3, KOH, MgCl2.

Hygroscopic Substances - substances absorb water from air, but not enough to form solutions. Examples of such substances include CaO, NaNO3, NaCl, Sucrose and CuO. Also, certain liquid substances absorb water from the air to get diluted - these are also regarded as being hygroscopic. Example, conc. H2SO4 and conc. HCl.

lf a hydroscopic substance absorbs so much moisture that an aqueous solution is formed, the substance becomes deliquescent.
