The solutes is greater outside the cell
The main objective of this experiment is to get a first hand look at osmosis by covering your egg in different solutions. Another purpose is to decide if the water, syrup, or the vinegar is a isotonic, hypertonic or hypotonic solution based on the reaction the egg has to the solution. The egg is portraying a cell. The cell membrane controls the movement of substances in and out of cells and organelles (Wikipedia). Selectively permeable membrane is one that allows some atoms/molecules to pass through it by the means of active or passive transport. Passive transport is the movement of some substances across cell membranes without need of energy input. Diffusion is the net passive movement of particles from a region in which they are in higher concentration to regions of lower concentration. Osmosis is a net movement of solvent molecules through a semipermeable membrane into a region with higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Hypertonic is is one where the concentration of solutes is greater outside the cell than inside it. Hypotonic is a solution that has less solute and more water than another solution. Isotonic is a type of solution that doesn’t affect the cell nor the solution. When a cell is placed in hypertonic solution it will do just the opposite to a cell since the concentration of solutes is greater outside of the cell than inside. When a cell is placed in an isotonic solution that means the amount of stuff inside the cell and outside the cell is equal (Enotes.com). When a cell is placed in a hypertonic solution the water will rush out of the cell, and it will shrivel up. When you first place the egg in vinegar, carbon dioxide is produced as the acidic vinegar reacts with the eggshell. As the egg sits in the vinegar, the shell is slowly dissolving away, producing a shell-less egg(ScientificAmerican.com). The eggshell should be totally gone by the third day, with a blob of egg white and yolk remaining inside a thin see through membrane.
