    Effect of Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg

    Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for

    Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference

    Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this
