Egg Osmosis Lab Report Central Questions: Is there an expansion or shrinkage limit on a chicken egg and if so what is it? What is the tonicity of the unknown solution? Hypothesis: If a deshelled chicken egg is placed in a hypotonic solution, as water flows into the egg the continuous build-up of water will result in the internal environment of the egg becoming hypotonic, and the process will After watching the demo video, write a typed written document (1 to 2 pages) that discusses all points below: What is the reaction that took place on Day 1? Explain the phenomenon of osmosis. 2) Eggs were soaked for 24 hours in each solution and measurements were taken before and after. During the process of diffusion, molecules concentrated in one area move to an area with a lower concentration until they reach a natural equilibrium. Osmosis is the movement of water molecules across a selectively permeable membrane, from an area of higher water concentration to an area of lower water concentration. If vinegar can do that to an egg, what else do you think it could do? In other words, osmosis is the diffusion of water. It aims to demonstrate how a semipermeable membrane regulates what enters and exits a cell through osmosis. Download the Rubber Egg PDF(595 Kb). Vinegar in fact contains acetic acid and this reacts with the calcium carbonate making up the shell of the egg.

Eggs are de-shelled using vinegar and then weighed before and after soaking. When you placed the egg in the three solutions, how do you think the concentration of solutes differed between the inside of the egg and outside of the egg? The egg membrane acts as a semipermeable membrane and keeps all of the dissolved solutes separated but allows the water to pass through. If you now put the egg in water, it will grow in size a lot more due to the much larger water concentration gradient across the membrane. Osmosis Through a Cell membrane of an Egg Joe Lockwood Introduction: When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane.
