Answer 2

Hygroscopy is a a phenomenon related to absorbing moisture from air.

• Hygroscopy is the phenomena of water molecules being drawn to and held by the surroundings, often at normal or room temperature, either through absorption or adsorption.
• Adsorbing compounds may undergo physical change, such as a change in volume, boiling point, viscosity, or another physical feature, if water molecules are suspended amid the molecules of the substance.
• Deliquescent substances are so hygroscopic that they can soak up water to the point where they turn liquid and create an aqueous solution.

• Sugar, caramel, honey, glycerol, ethanol, wood, methanol, sulfuric acid, numerous fertiliser chemicals, numerous salts (like calcium chloride, bases like sodium hydroxide, etc.), cellulose fibres (such as cotton and paper), and a wide range of other substances are examples of hygroscopic substances.
• A chemical is said to be hydrophilic if it dissolves in water.
• Due to their extreme hygroscopicity, zinc chloride, calcium chloride, potassium hydroxide, sodium hydroxide, and many other salts easily dissolve in the water they absorb. This trait is known as deliquescence.
• In addition to being hygroscopic in concentrated form, sulfuric acid solutions are also hygroscopic at concentrations of 10% v/v or below.
