Deliquescent AND Hygroscopic:
Deliquescent substances are solid matter that can get dissolved by absorbing water vapor. The resulting solution is an aqueous solution. This process is known as deliquescence. These deliquescent substances have a high affinity to water.
for example: sodium hydroxide, potassium hydroxide, ammonium chloride, sodium nitrate, calcium chloride, etc.
Some examples: are Zinc chloride (ZnCl2), sodium chloride (NaCl) and sodium hydroxide (NaOH).

Hygroscopic:
Hygroscopic substances are solids that can absorb or adsorb water from its surroundings. When water vapor is absorbed by hygroscopic substances, the water molecules are taken into the spaces of the crystal structure. This causes the volume of the substance to increase. Hygroscopy can result in changes in the physical properties of the hygroscopic substances; such properties include color, boiling point, viscosity, etc.
