Abstract
Throughout the process of this experiment, chicken eggs were used to test how well certain solutions would be absorbed. The objective was to determine the rate and direction of osmosis into and out of cells according to their diffusion gradients. During this experiment eggs were rolled on paper towels to blot the excess liquid and then weighed. They were then placed into one of six solutions immediately afterwards. In 15-minute intervals, the eggs were blotted and weighed again. This process was repeated four times, adding up to 60 minutes.
Through the results, we proved that distilled water and 10% sucrose solutions made the …show more content…
This process showed how each solution affected the egg’s rate and direction. Osmosis is the diffusion of water across a differentially permeable membrane. Moving across a semi-permeable membrane, the water diffuses from a range of high concentration to a range of low concentration. This is made possible by the presence of a concentration gradient. For this experiment, the eggs were examined due to the shifting of the solution across the membrane. Which sucrose solution makes the egg gains the most weight? Lose weight? My hypothesis was that as time increased, the weight in all of the eggs would increase as well. With the eggs being soaked in different solutions, it caused me to conclude that all of the eggs would absorb some …show more content…
The distilled water and 10% sucrose solutions made the eggs gain weight because they are hypotonic solutions. A hypotonic solution is any solution that has a lower osmotic pressure than another solution. The distilled water passed through the semi-permeable membrane the most. The 20%, 30%, 40%, and the unknown sucrose solutions made the eggs lose weight because they are hypertonic solutions. A hypertonic solution is any solution that has a higher osmotic pressure than another solution. We concluded that distilled water gained the most weight and 30% and 40% sucrose lost the most weight. My hypothesis, each egg would gain weight, proved to be unverified after conducting this experiment due to the loss in
