Question

After the egg has been in the vinegar for three days, remove the egg. Turn on the flashlight or desk lamp, and shine it on the egg. Write down what the egg looks like?

Answer 1

An egg in vinegar for three days will appear translucent when illuminated due to the shell dissolving, leaving a semi-permeable membrane that allows light to pass through.

Step-by-step explanation:

When an egg is left in vinegar for three days and then illuminated by a flashlight or desk lamp, the egg will likely appear translucent. The shell of the egg, which is made of calcium carbonate, reacts with the acetic acid in vinegar to produce carbon dioxide gas, water, and a compound called calcium acetate. This reaction causes the shell to dissolve, leaving behind the semi-permeable membrane. The light passing through the egg will make it look like a glowing orb, possibly with a slight coloration depending on the color of the yolk visible through the membrane.
