Which option correctly describes the effect of dilution on molarity?
Answer and explanation
Correct answer: If moles remain same and volume increases, molarity decreases
Molarity is n/V. During ordinary dilution, solvent is added, so the moles of solute remain constant while the solution volume increases. With the same numerator and a larger denominator, n/V becomes smaller. Hence A is correct. Dilution does not create additional solute, and it certainly does not make the volume zero.
