Given below are some solutions. Identify and write down the solvent and the solute present in them. (Hint: Those present in large amount is the solvent and that in small amount is the solute).

Write down the observation in the table given below, when 1mL Barium chlo-ride solution is added to the solutions given in the table.

Assertion : Larges the value of cryoscopic constant of the solvent lesser will be the freezing point of the solution Reason : Depression in the freezing point depends on the nature of the solvent. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A). c)If (A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.

How will these colloidal solutions respond to addition of small amount electrolyte solution into each?

Mr. Raju has determined the molecular masses of different solutes in different solvents by osmotic pressure measurements and present them in the following table. Please help him to complete the table .
