Hint: The deliquescent substances absorb moisture from the atmosphere and form a solution. Table salt is a chemical compound with sodium chloride $ \left( {NaCl} \right) $ with impurities like calcium chloride and magnesium chloride which are deliquescent substances.
Complete Step By Step Answer:
Some of the chemical compounds are deliquescent substances. These substances absorb moisture from the atmosphere and form a solution. The pressure exerted by a substance in its vapor state is known as vapor pressure, the vapor pressure of the solution that was formed from deliquescent substances has a less partial pressure of water vapor present in the air in this case only the deliquescence occurs.
Sodium chloride is an ionic salt with a chemical formula of $ NaCl $ . But this table salt consists of some impurities like calcium chloride $ \left( {CaC{l_2}} \right) $ and magnesium chloride $ \left( {MgC{l_2}} \right) $ .
Both chemical compounds calcium chloride and magnesium chloride are deliquescent substances. Thus, both substances absorb moisture and form a solution.
In the rainy season, water will be present as vapor in the atmosphere, this water vapor can be absorbed by these impurities present in table salt and forms a solution.
Thus, due to the presence of impurities in table salt, it gets wet during the rainy season.
Note:
Table salt can be used mainly as a preservative in foods, it helps in preventing the spoilage of foods. Salt is also used in the fermentation process like pickles. Due to the presence of sodium in sodium chloride, it is an essential substance to humans.
