The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked for 30 minutes.
The change in the mass of the eggs varied widely depending on the concentration of sucrose that they were placed in. The mass of the eggs placed in the 0%, 10%, and 20% sucrose solutions increased in mass between their initial and 30 minute measurements. The eggs placed in the sucrose solutions of 30% and 40% lost mass after 30 minutes. The difference in the masses can be explained by the process of osmosis. Osmosis is a spontaneous process in which a solution wants to move to into an area in which the concentration is higher. …show more content…
The eggs that were placed in the higher concentration lost more of the solution because the solution outside of the egg was greater than that on the inside. The eggs that were put into the lower concentrations absorbed more sucrose because the concentration inside was less than the outside and the natural tendency is to move into areas that have a higher concentration. This is because the levels of sucrose on the inside of the eggs was higher than that of the
