Final answer:
The egg soaked in vinegar will likely expand due to osmosis, as water from the vinegar, which is about 95% water, moves into the egg to equalize solute concentration differences. Correct option is A.
Step-by-step explanation:
Your hypothesis for what will happen to the egg soaked in vinegar is likely that the egg will expand due to osmosis. Vinegar is an acetic acid solution in water. Typically, vinegar is about 95% water and 5% acetic acid. Due to osmosis, which is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, the water in the vinegar outside the egg will move into the egg, causing it to expand.
For example, when placing red blood cells in a hypotonic solution, such as pure water, we expect them to swell and potentially burst because the concentration of solutes inside the cell is higher than that in the surrounding water, prompting water to rush into the cell. This process is known as hemolysis. Similar principles apply to the egg in vinegar; however, an egg's membrane differs from that of a red blood cell, so it might not burst but will likely swell significantly.
