Question

Consider the following statements regarding osmotic pressure:
(A) Molar mass of a protein can be determined using the osmotic pressure method.
(B) The osmotic pressure is proportional to the molarity.
(C) Reverse osmosis occurs when a pressure larger than osmotic pressure is applied to the concentrated solution side.
(D) Edema occurs due to retention of water in tissue cells as a result of osmosis.
Choose the correct statements with reference to osmotic pressure:

• A. (A), (B), and (D) only
• B. (A), (B), and (C) only
• C. (A), (B), (C), and (D)
• D. (B), (C), and (D) only

Answer 1

Answer: (C)

(A), (B), (C), and (D)

Answer 2

All the statements are correct regarding osmotic pressure:(A) The molar mass of macro-molecules like proteins can be determined using osmotic pressure.(B) Osmotic pressure isdirectly proportional to molarity (concentration).(C) Reverse osmosis occurs when externalpressure greater than the osmotic pressure is applied to the concentrated solution.(D) Edemais a condition where excess water is retained in tissues due to osmosis.
