Density Of Egg Lab

Decent Essays
During the course of this experiment, we handled multiple eggs without knowing factors like age, freshness, and what type of eggs they were. One thing that can be deduced though, is that these eggs will all observe the same type of changes over time. The major change within this experiment relates to the density of the eggs that were observed. All eggs over time begin to spoil due to a chemical reaction that causes their density to change. Eggs are “slightly porous” which means that over time small amounts of air can pass through the membrane of an egg. Though, as the air is passing through the membrane carbon dioxide and liquid from inside the egg moves outwards. This loss in matter is eventually what causes the eggs density to change over…show more content…
This further reinforces the thought that the eggs with a density over one are fresh while eggs with a density lower than one are on the rotten side. Egg C specifically was determined to be not fresh as it was floating in pure ethanol. There are many different ways that one could possibly measure the density of an egg, but the procedure in which we used water as a medium can proved to be very helpful. The conversion factor for the density of water is equal to one gram of water per one milliliter of water. When placing an egg in water, you can determine the density of an egg by whether it floats or not. If the egg floats, the density of the egg is under one gram per milliliter and the egg is most likely not fresh enough to consume. On the other side, is the egg sinks to the bottom of the water, it’s density is over one gram per milliliter and is fresh enough to eat. Throughout this experiment, parts of the procedure have emulated ways in which green chemistry is present in things that are performed in the lab. The big four in this experiment include preventing waste, designing benign chemicals and design for
