What will happen to a hard-boiled egg if placed in a beaker of saltwater?
Correct answer
B
Rationale
When a hard-boiled egg is placed in a beaker of saltwater, a hypertonic solution, water will move out of the egg through osmosis. The saltwater's higher solute concentration causes water to leave the egg in an attempt to balance the concentrations, resulting in the egg losing water and shrinking, leading to it shriveling.
