On our first day, the egg in the vinegar increased in size and the eggshell dissolved. This happened because of the calcium carbonate in the shell of the egg and the acid in the vinegar. This is hypotonic because it causes the water to move through in the egg which causes the egg to get bigger in size. The mass of the first cup was 13.1g and the mass of the raw egg was 59.3g. After the egg and vinegar experiment, the mass of the new cup was 11.3g and the mass of the “shell-less” egg was 92.2g. On our second day, the egg in the corn syrup decreased in size. This happened because the corn syrup contains mostly sugar. This is hypertonic because the corn syrup has a high concentration of dissolved molecules of sugar and the water moved out of the egg. The mass of the cup was 10g and the mass of the egg was 59.7g. The percent change in mass of egg from day 1 to day 2 was 55.48%. …show more content…
This is isotonic because there were no movement of water and the water molecules were only moving inside the egg instead of moving out of the egg. The mass of the day 2 cup was 11.3g and the mass of the egg was 149.3 g. The percent change in mass of egg from day 2 to day 3 was 35.25%. On our fourth day, the egg in the lemonade increased in size and it gained more mass. This is because of the acid from the lemonade juice that made the egg enlarged. The mass of the cup was 10g and the mass of the egg was 106.4g. The percent change in mass of egg from day 3 to 4 was
