Hygroscopicity is defined as absorb moisture. With sugar being solid, it absorbs moisture in its surrounding (air). Therefore, sugar is hygroscopic because it is solid that â¦does not contain much moisture.
We have examples of deliquescent such as calcium chloride, ferric chloride, magnesium chloride, zinc chloride, potassium carbonate, potassium hydroxide and sodium hydroxide.xamples of several known hygroscopic compounds are: 1  Sodium chloride (halite) (NaCl). 2  Calcium chloride (CaCl2). 3  Sodium hydroxide (NaOH). 4  Sulfuric acid (H2SO4). 5  Copper sulphate (CuSO4). 6  Phosphorus pentoxide (P2O5 or more correctly P4O10). 7  Silica gel. 8  Hydrated salts such as Na2SO4â10H2O.
