WebAug 27, 2024 · Salt, Sugar and Pure Water – Osmosis, the process in which solvent molecules move from an area of lower solute concentration to an area of higher solute concentration, can easily be demonstrated with potato experiments. Potatoes are full of both water and starch, and will gain water when immersed in watery solutions. WebSep 14, 2024 · A hypotonic solution is one that has a concentration of solute that is lower than the amount of solute inside of the potato’s cells. This causes water to move into the cells in attempt to reach osmotic equilibrium. The cells will swell with the excess water, causing the potato cube to swell. Table of Contents show.
