Question 22

The egg is immersed in a hypertonic solution.

A hypertonic solution has a higher concentration of solutes compared to the inside of the egg, leading to water moving out of the egg and causing it to shrink.

A) Hypertonic

This option is correct because a hypertonic solution causes water to move out of the egg, resulting in a decrease in its volume. The scenario suggests that the concentration of solutes outside the egg is greater than that inside, which is the defining characteristic of a hypertonic environment.

B) Isotonic

This option is incorrect since an isotonic solution has equal concentrations of solutes inside and outside the egg. In such a scenario, there would be no net movement of water, and the egg would neither swell nor shrink, which contradicts the effects described in the scenario.

C) Hypotonic

This option is also incorrect because a hypotonic solution has a lower concentration of solutes compared to the inside of the egg. In a hypotonic environment, water would move into the egg, leading to swelling or bursting, which does not align with the implications of the egg's condition in the question.

D) None of the above

This option is incorrect as it suggests that the solution does not fit any type, which is false. The scenario clearly indicates that the egg is in a hypertonic solution, making this option invalid.

Conclusion

The correct answer is hypertonic, as it accurately describes the condition of the solution surrounding the egg, leading to water exiting the egg and causing it to shrink. All other options do not align with the observed effects on the egg and therefore fail to correctly represent the scenario.
