7) Biology students used raw eggs in an experiment on tonicity and osmosis. The students put their eggs into vinegar to remove the shells. The vinegar was used to remove the shell from the raw egg. What other effect(s) did the vinegar have on the egg? A) The vinegar solution was hypotonic, causing the egg to gain mass. B) The vinegar solution was hypotonic, causing the egg to lose mass. C) The vinegar solution was hypertonic, causing the egg to gain mass. D) The vinegar solution was isotonic to the egg so the mass remained constant.

The vinegar solution was hypo-tonic and hence this leads the egg to gain mass
Explanation:
• First vinegar acts on the outer covering of the shell causing the egg shell to dissolve in water
• Then the raw egg reacts with the vinegar solution and the outer membrane of the egg becomes hard
• Then the egg is observed to have gained weight and thus due to the process of osmosis the reaction has occurred
• Through the process of diffusion the solution is diffused from a region of higher to lower concentration and it has gained weight
