  • question_answer Why does table salt get wet in rainy season?

    Answer:

                    Pure NaCI is not hygroscopic but table salt is impure NaCl containing impurities of\[M{{g}_{2}}S{{O}_{4}},\,\,CaS{{O}_{4}},\,\,MgC{{l}_{2}}\] and \[CaC{{l}_{2}}\]. All of these being hygroscopic absorb moisture from air in rainy season. As a result, table salt gets wet.
