Biology coursework: effect of sugar solution on potato chips planning before planning the experiment, i will research osmosis, so that i can make predictions. Osmosis osmosis: the movement of a little dissolved salt produces a dilute solution with a high water concentration a lot of dissolved salt produces a concentrated solution with a low water concentration osmosis the animation models how osmosis works. As water passes through the membrane to the salt solution, the level of liquid in the saltwater compartment will rise until enough pressure, caused by the difference in levels between the two compartments, is generated to stop the osmosis.

Osmosis and dialysis osmosis is the tendency of water in salt water to flow from an area of low salt concentration to an area of high salt all solutes, not just salt salt in solution is comprised of sodium and chloride ions, dissolved salt will be referred to for simplicity. Biology coursework-osmosis osmosis can also be seen very effectively when potato slices are added to a high concentration of salt solution the water from inside the potato moves to the salt solution.
Osmosis always moves a solvent in one direction only, from a less concentrated solution to a more concentrated solution as osmosis proceeds for example, jellyfish that live in salt water have much higher salt-to-water solute concentrations than do freshwater creatures other.
