Question

diffussion pressure of pure solvent is

Answer 1

Response. DPD or diffusion pressure deficit is the difference between the diffusion pressure of a solution and a pure solvent when both are subjected to the same atmospheric pressure. Since pure water does not contain any solute particles, therefore it has zero DPD.

Answer 2

1245.69 atm

Reason:-

Diffusion pressure deficit or Diffusion pressure of pure water is maximum and its theoretical value is 1245.69 atm at STP. For pure water DPD and Diffusion pressure are same. DPD of a solution is equal to its osmotic pressure i.e. DPD = OP(of solution).
