How does osmolarity affect osmosis?

1 Answer

Osmolarity is an old term for osmotic concentration. This can be used to measure the amount of solute (think sugar) dissolved in a solvent (water).

If the level of solute of a solution is higher than the concentration of solute inside of the cell, water will flow out of the cell during osmosis. See egg in syrup in the video below.

If the level of solute outside the cell is lower than the levels of solute inside of the cell, water will flow into the cell. See the egg when placed into distilled water in the video.

Here is a video of a lab conducted to test osmosis in eggs placed into different solutions.
