An Intiative by Sri Chaitanya

Volume of both KCl and $A l C l_{3}$ solutions will increase

Final volume of $A l C l_{3}$ solution will be $\frac{400}{3} m l$

Decrease in volume of urea solution with respect to initial solution is $\frac{100}{3} m l$

There will be no change in volume of KCl solution.

Detailed Solution

Ans. (A,B,C)
After sufficient time osmotic pressure of all solution will become same. As T is same molar concentration should be same, for this ratio of volume should be the same as that of moles ratio.
Urea : KCl : AlCl
20 m moles 30 m moles 40 m moles
Total volume (300 ml) should be divided in
