Question

A deshellled, raw egg is placed in a beaker of 75% sugar solution. Which of the following best describes what will happen to this egg?
A. The egg will have the same mass
B. The egg will gain mass because the sugar will cross the membrane into the egg.
C. The egg will lose mass because the water will cross the membrane into the beaker.
D. None of the above.

Answer 1

C. The egg will lose mass because the 75% sugar solution is hypertonic; water will move out of the egg through the semi‑permeable membrane by osmosis toward the higher solute concentration. Sugar molecules are too large to cross the membrane, so they do not move into the egg.
