What is Osmosis ?

Osmosis is the movement of water across a semi-permeable membrane from a high concentration to a low concentration area, aiming to equalize water concentration on both sides. This process is illustrated using an egg experiment, where the egg expands when placed in water and shrinks when placed in corn syrup due to water moving in and out of the egg based on the concentration differences.

Osmosis Definition

• 00:00:14 Osmosis is the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration. This process occurs to equalize the concentration of water on both sides of the membrane. It's like people moving from a crowded room to a less crowded room through a selective door.

Egg Experiment

• 00:00:56 An egg experiment demonstrates osmosis. When the egg is placed in water, it expands because water moves into the egg from a high concentration outside to a lower concentration inside. Conversely, when placed in corn syrup, the egg shrinks because water moves out of the egg into the corn syrup, where water concentration is lower. Finally, in distilled water, the egg expands again as water moves from a high concentration outside to a lower concentration inside.
