Ncert Exercises & Solutions

At a given temperature, osmotic pressure of a concentrated solution of a substance:

1.	is higher than that of a dilute solution.
2.	is lower than that of a dilute solution.
3.	is same as that of a dilute solution.
4.	cannot be compared with osmotic pressure of dilute solution.

HINT:

π

α

Concentration

Explanation:

According to definition of osmotic pressure we know that

π

= CRT. For concentrated solution C has higher value than dilute solution.

Hence, as concentration of solution increases osmotic pressure will also increase.
