Assertion (A): When common salt is kept open, it absorbs moisture from the air.
Reason (R): Common salt contains magnesium chloride.
The correct answer is option 'A' - Assertion (A) is true but reason (R) is false.
Explanation:
1. Assertion: When common salt is kept open, it absorbs moisture from the air.
When common salt is exposed to the air, it tends to absorb moisture from the surrounding environment. This is because common salt, or sodium chloride (NaCl), is a hygroscopic substance. Hygroscopic substances have the ability to attract and retain water molecules from the air.
2. Reason: Common salt contains magnesium chloride.
The reason given for the assertion is that common salt contains magnesium chloride. However, this reason is incorrect. Common salt, which is sodium chloride (NaCl), does not contain magnesium chloride. Magnesium chloride is a different compound altogether. It is a salt composed of magnesium and chlorine ions (MgCl2).
So, the reason given in statement (R) is false as common salt does not contain magnesium chloride.
Conclusion:
In conclusion, the assertion (A) is true because common salt does absorb moisture from the air. However, the reason (R) is false because common salt does not contain magnesium chloride. Therefore, the correct answer is option 'A' - Assertion (A) is true but reason (R) is false.
Reason (R): Common salt contains magnesium chloride.

Assertion (A) is true. When common salt, also known as sodium chloride, is exposed to humid air, it absorbs moisture from the air. This is because the salt molecules are hygroscopic, meaning they have a tendency to absorb water from the air.
Reason (R) is false. Common salt does not contain magnesium chloride. It is a compound of sodium and chlorine, with the chemical formula NaCl.
Therefore, the correct answer is (1) Assertion (A) is true but reason (R) is false.
