Analyzing Various Permeable Bags Placed in Different Concentrations of Water and Sucrose

Introduction
Osmosis is defined as the movement of water from a region of water that has a higher potential to a region of water that has a lower potential through semipermeable membranes. There are three types of solutions, hypertonic, hypotonic, and isotonic. Hypertonic solutions have a higher concentration of solute while hypotonic solutions have a lower concentration of solute. Isotonic solutions have an equal concentration of solute. There is no net movement going in or going out of the isotonic solution or solute. The purpose of this experiment is demonstrate osmosis by weighing the dialysis bag to indicate whether or not the bag is hypotonic, hypertonic or isotonic in the different concentrations of water and sucrose. By carrying out this experiment we will be able to better understand how the process of diffusion and osmosis works. My hypothesis is that diffusion will continue to occur throughout these various mixture of concentrations in the dialysis bags until equilibrium is reached. Once equilibrium is reached there should not be any net movement. Therefore, I predict that the bag with the higher concentration of sucrose will turn out to be hypertonic and while the lower levels of dialysis bags with sucrose will end up being hypotonic. The dialysis bag with water will turn out to be isotonic while the beaker with 60% sucrose solution and the dialysis bag filled with water…
