Question

Many salts absorb water from the atmosphere. This property is called:
A. Hydration
B. Dehydration
C. Deliquescence
D. Efflorescence

Answer 1

We know that salt has a high capacity for its surroundings to absorb water. It can also become deliquescent above a relative humidity of around $75\%$ salt, which means it takes up so much water that it becomes a solution. Sugar is also hygroscopic; it forms weak bonds with its surrounding water molecules. Water-absorbing materials include: sponge, napkin, paper towel, face cloth, sock, paper, balls of cotton. Styrofoam, zip-lock envelope, wax paper, aluminium foil, sandwich wrap; fabrics that do not absorb water. He participated in some free play to wrap up our water absorption experiment.

Complete step by step answer:
By absorbing humidity from the air, delicate salts have a good preference for moisture and become liquid. In nature, it is hygroscopic, e.g. calcium chloride, zinc chloride, sodium hydroxide, magnesium chloride.
Those which absorb moisture from their surrounding environment are delicate salts or substances. It has the ability to dissolve and form its own solution in the absorbed humidity. Sodium Nitrate, Calcium Chloride, and Potassium Oxide are some examples.
Deliquescent is the property which makes salts absorb water.
Option C deliquescence is correct as is the property which helps water to absorb water from the atmosphere.

So, the correct answer is Option C.

Note: We need to know that when more water and fluids exit the body than join it, dehydration occurs. Headaches, lethargy, and constipation may be triggered even by low dehydration levels. The body of a human being is around $75\%$ water. It cannot live without this water. Within cells, inside blood vessels, and within cells, water is discovered. Efflorescence is a powdery or crystalline salt layer often visible on the surfaces of concrete, brick, stucco, or natural stone. It happens when water on the masonry surface leaves behind salt deposits.
