Egg Osmosis Lab Report

Conclusion

(1) In the osmosis lab I made a few predictions (a) I predicted that the egg in the hypotonic solution will swell & gain mass because, there are more h20 molecules and less solutes in the distilled water then inside the egg therefore the h20 will go into the egg. (b) I predict that the egg in the hypertonic solution will shrink and lose mass because, there are more salt molecule (solution) and less water molecules in the salt than inside the egg therefore the h20 will the egg. (c) I predict that the egg in the isotonic solution will stay the same size & mass because, there will be the same amount of solutes & H2O inside and outside the egg therefore the H2O will go inside & outside the egg. (2) My hypothesis was not supported by

So when you drink a lot of water and don't balence it with something salty then you could be potentially over hydrated. with that dehydration is when someone doesn't have enough water and can be very unhealthy. By being dehydrated it can cause muscle cramps and fainting. The egg could also be perfectly balanced with a perfect amount of solutes and h2o in the solution to cause to the egg to not change weight. The egg in the lab is doing the same thing our blood cells do everyday. The egg in the osmosis lab is doing the same actions because the shell around the egg is a form of a cell membrane a stretchy substanse like elastic that can expand to a certain point. With this substance the egg can expand and shrink to whatever point its capable of. When the egg was in the hypertonic solution, it was supposed to shrink, but it had gained mass instead. By that I mean the balance was off there was too much water inside the egg then outside. If there was more water outside the egg, the egg would have shrunk a lot. But water makes the egg expand and gain mass. Therefore In the hypotonic solution the egg was supposed to gain in mass, but instead it decreased in mass. The egg mass didn't have a drastic change, but it still was
