The lab was designed to show an example of osmosis. Osmosis is the diffusion of water across a semipermeable membrane. The experiment last three days in which a egg was test in different solutions. On the first day, the question answered was what will happen to an egg when placed in vinegar. Before beginning the experiment a hypothesis had to be made. It was hypothesized that by placing an egg in vinegar the vinegar would dissolve the eggs shell due to its acidic properties. On the second day, the main question was what would happen to the egg’s size when placed in hypertonic solution such as saltwater vs a hypotonic solution such as syrup. The hypothesis was that the egg would lose mass from the saltwater solution from the salt drawing out water from the cell and the egg would gain mass in the sugary syrup solution. The first day a 32 ounce mason jar was used. Two eggs were carefully placed in the jar and filled with white vinegar. A cap was placed tightly on top and the jar was placed on the countertop for 24 hours. On the second day observations were made to the jar. There were many bubbles around the eggs and the jar. The eggs were carefully removed and examined and weighed. Two 32 ounce mason jars were then taken. One was filled with salt water and the other was filled with syrup. A egg was placed in each solution and placed back on the countertop for 24 hours. On the third day the eggs and jars were examined. First the egg in the saltwater was removed and weighed it appeared to be visibly larger in size. Next the egg in the syrup was removed and weighed and was visibly darker and smaller in size. Lastly the eggs were weighed. The decalcified eggs after being placed in the vinegar had a weight of 1) 69g and 2) 70g. The weight of the egg after placed in saltwater has a resulting weight of 1)78g and the resulting weight of the the egg being in syrup 2)52g. When the egg cell was placed in saltwater for 24 hours the egg gained ma
