Question

Assertion: If volume of a solution changes by 20%, then molar conc.
of the solution changes by 20%.
Reason: The no of moles of solute in the solution does not remains the same on dilution.

Answer 1

Answer:

Normality is defined as number of mole equivalents of solute per liter of solution and molarity is defined as number of moles of solute dissolved per liter of solution.So if we add more solvent then volume of solution increases which will affect not only nomality or molarity but also affects molality.
