Question

What statement can be cited for 10% sodium
chloride solution and 10% sugar solution present?
(a) Both have equal OP
(b) The concentration of sodium chloride
solution will be less than concentration of
sugar solution
(c) The OP of sugar solution will be higher than
OP of sodium chloride solution
(d) DPD of sodium chloride solution will be
higher than DPD of sugar solution

Answer 1

The statement that can be cited for 10% sodium chloride solution and 10% sugar solution present is:

(d) DPD of sodium chloride solution will be higher than DPD of sugar solution

• DPD is the acronym for Diffusion pressure deficit

• It refers to the deficit in osmotic pressure which is caused due to the presence of molecules of solute in the solution.

• The deficit will increase with the increase of solute particles.

• Therefore, in the given solutions DPD of sodium chloride solution will be higher than DPD of sugar solution. This is because sugar molecules will not split while sodium chloride molecules will split into 2 ions.

Answer 2

DPD of sodium chloride solution will be  higher than DPD of sugar solution.

Option (D) is correct.

Explanation:

• Diffusion pressure deficit (DPD) is the deficit in osmotic pressure caused due to presence of solute molecules in the solution.
• More the number of solute particles greater will be the deficit.
• In the given two solutions, the sodium chloride molecule will split into two ions, one sodium ion and another chloride ion.
• The sugar molecule will not split.
• The number of particles in sodium chloride solution will be twice the number of particles in sugar solution.
• Consequently, the DPD of sodium chloride solution will be higher than DPD of sugar solution.

Thus DPD of sodium chloride solution will be  higher than DPD of sugar solution.
