Dr. Olga Jarrett discusses with the class an exercise with eggs which have had their shells removed.
Students made measurements to characterize the eggs (e.g., mass, size, ...) before placing them into solutions of various natures and concentrations. One of the fluids for immersion was syrup, as shown at right above.
Two eggs with shells were placed in vinegar. Why is one floating and the the other submerged? As a hint, the submerged egg has just been wiped off and reinserted into the vinegar (acetic acid) solution. With that hint, interpret what you see.
