consider 0.1 M solutions of two solutes X and Y. The behaves as a univalent electrolyte while the solute Y dimerises in solution. Which of the following statement are correct regarding these solutions? (1) The boiling point of the solution of X will be higher than that of Y (2) The osmotic pressure of the solution of Y will be lower than that of X (3) The freezing point of the solition of X will be lower than that of Y (4) The relative lowering of vapour pressure of both the solutions will be the same (a)1, 2 and 3 (b)2, 3 and 4 (c)1, 2 and 4 (d)1, 3 and 4

Study the following figures and select the correct statements regarding these. (i)A shows mode of asexual reproduction in sponges through internal buds. (ii)B shows sexual reprodction through zoospores in Chlamydomonas. (iii) C shows asexual reproduction through fragmentation in Penicullium. (iv) D shows external budding in Sycon.

Solute A is a ternary electrolyte and solute B is non-elctrolyte . If 0.1 M solution of solute B produces an osmotic pressure of 2P ,then 0.05M solution of A at the same temperature will produce on osmotic pressure equal to

van't Hoff proved that osmotic pressure ( pi ) is a colligative property. For an ideal solution, osmotic pressure( pi ) is helpful to determine that molecular mass of solute using M_(B)=(W_(B)RT)/(pi.V) Relation can exxpressed by the curve (C = concentration) :

Statement-I: 1M solution of Glauber's salt is isotonic with 1M solution of KNO_(3) . Because Statement-II: Solutions having same molar concentration of solute may or may not have same osmotic pressure.
