Isotonic solutions must have the same………..

Options

A. solute
B. density
C. elevation in boiling point
D. depression in freezing point

Answer

C, D

Explanation

Isotonic solutions have same osmotic pressure and same concentration. Elevation in boiling point and d epression in freezing point are the colligative properties. Thess two colligative properties depend upon concentration.
As the molar concentration is same for isotonic solutions, so elevation in boilling point and depression in freezing point of istonic solutions must be same.
