Question 13
At a given temperature, osmotic pressure of a concentrated solution of asubstance.......... .
(a) is higher than that of a dilute solution
(b) is lower than that of a dilute solution
(c) is same as that of a dilute solution
(d) cannot be compared with osmotic pressure of dilute solution.

Answer 1

(a) According to definition of osmotic pressure we know that $\pi =CRT.$ For concentrated solution C has higher value than dilute solution.
Hence, as concentration of solution increases osmotic pressure will also increase.
