Discussion
Assertion (A) : When common salt is kept open, it absorbs moisture from the air.
Reason (R) : Common salt contains magnesium chloride.
Answer: A
Correct answer: Both A and R are true and R is the correct explanation of A.
Common salt as sold contains traces of magnesium chloride, which is deliquescent - it absorbs moisture from the air until it dissolves in it. Pure sodium chloride does not do this, so the impurity is exactly the reason for the caking. Both are true and R explains A.
