Conclusion
This experiment demonstrated the process of osmosis as water particles passed through the egg’s selectively permeable membrane depending on the circumstances – the concentration of the water. The water in the beaker would pass through the egg’s membrane when it had a low concentration in order to balance out the concentrations of the egg and the water in the beaker, while water in the egg would pass through its selectively permeable membrane when the water outside the beaker had a higher concentration in order to balance the concentration out again. In this experiment, my hypothesis was not supported, as the amount of solute in the salt water was lacking due to an error. Otherwise, all variable were controlled, such as the amount of water in the beakers, the room temperature, and the egg size (similar). With independent variable of the varying concentration, the mass of the eggs were affected as well as the volume remaining and their appearance. There was a gain in mass and size for both eggs, although more for Egg 1, the egg within the coloured water.
