Students used eggs to observe the effect of osmosis on cells. in the experiment, the egg represented a typical cell. before beginning the experiment, students soaked the raw eggs overnight in vinegar to remove the shells. after the shells were removed, students obtained the mass of the shell-less eggs. students then soaked the eggs in a variety of solutions: vinegar, 10% salt water, corn syrup (kayro), and distilled water. after 24 hours, the eggs were removed from their respective solutions, dried off, and massed. the results are recorded in the data table provided. based on the results, what type of solution is the salt water? a) the salt water is hypotonic because it has less solutes than the egg. b) the salt water is isotonic because there is no mass change in the egg. c) the salt water is hypertonic because it has more solutes than the egg. d) the salt water is hypertonic because there is no mass change in the egg.
