Question

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.

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. A hypotonic solution has a lower solute concentration compared to the inside of the egg. When an egg is placed in a hypotonic solution like vinegar, water moves into the egg, causing it to gain mass.

Answer:

A. The vinegar solution was hypotonic, causing the egg to gain mass.
