Diffusion pressure of the pure solvent is

Question

Diffusion pressure of the pure solvent is (A) always more than its solution. (B) sometimes more than its solution. (C) less than its solution. (D) equal to its solution.

Substances having more solute concentration diffuse with low pressure. Pure water with no solute in it shows maximum D.P. Pure solvent has D.P = 1236 atm. Addition of solute decreases the D.P, therefore Solute is some time referred as DPD or Diffusion pressure deficient.
