Question

On mixing 30 mL of acetone with 20 mL of chloroform, the total volume of solution is:

• A. equal to 10 mL \hspace{0.5cm}
• B. less than 50 mL
• C. greater than 50 mL \hspace{1cm}
• D. equal to 50 mL

Hint:

When mixing liquids, the total volume may be less than the sum of the individual volumes due to intermolecular forces.

Answer 1

The Correct Option is B

Mixing acetone and chloroform results in a total volume reduction compared to the sum of their individual volumes. This occurs because of molecular interactions between the solvents, with the magnitude of the volume change contingent upon the degree of mixing and the nature of the solute-solvent interactions.
