Question

Osmotic pressure of a solution at a given temperature

• A. increases with concentration
• B. decreases with concentration
• C. remains same
• D. initially increases and then decreases

Answer 1

Answer: (A)

According to Boyle-van’f Hoff law, at constant temperature the osmotic pressure of a solution is directly proportional to its concentration and inversely proportional to its dilution $\pi \propto C$ (where $C$ = concentration)
Hence, the osmotic pressure of a solution at a given temperature increases with concentration
