Assiertion :When a concerntrated solution deluted bu adding more water, molarity of the solution remains unchanged. ltbtgt Reason : Products of moes of a solute and volume is equal to molarity.

Answer»

If both ASSERTION are REASON are correct and reason is correct explanation for assertion.
If both assertion and reason are corrct but reason is not correct explanation for assertion.
If assertion is corrct but reason is incorrect.
If assertion and reason both are incrrect.

Solution :Correct Assertion : Molarity of a solution DECREASES when concentrated solution is DILUTED by adding more.
