Question

State whether the following statements are true or false .
DPD of pure water is zero.

• A. True
• B. False

Answer 1

The correct option is A True

DPD or diffusion pressure deficit is the difference in the diffusion pressure of a solution and a pure solvent when both are subjected to the same atmospheric pressure. Since pure solvent has no dissolved solutes in it, therefore it will have maximum diffusion pressure and zero DPD.

So, the given statement is true.
