Egg Osmosis (Hypertonic vs. Hypotonic Solution)

[I made a mistake in calculating percent change. Percent Change = (Final Mass - Orginal Mass) / Orignal Mass. Sorry!]
To test the semi-permeable qualities of the inner membrane of an egg shell, I place one egg in a hypertonic solution (corn syrup) and one egg in a hypotonic solution (water).
Using time-lapse footage, you can watch one egg shrink in size and one egg increase in size due to osmosis (the movement of water through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration) in order to reach dynamic equilibrium (a state in which all regions have an equal solute concentration).

Btw, if water did move from a region of high solute concentration, then the solute concentration on that side would be even higher, thus not achieving dynamic equilibrium.

[@stethoscopembrn2658]

You're welcome

[@XoletteScience]

Thank you, but it is correct. Osmosis is the movement of H2O through a semi-permeable memrbrane in which H2O will tend to move towards the higher solute conc. (if the conc are uneven) to reach dynamic equilibrium. Once that state is reached, the water will still move but equally in both directions. Active transport is the movement of PARTICLES (not water) from a low solute concentration to high solute concentration, but requires energy. Osmosis doesn't require energy.Thank you for the comment!

Yes, as long as the solution is hypertonic, meaning it has a A LOT of solute (like salt) then you're good to go. I've done this experiment before with water and sugar as my solution, and I feel that the corn syrup has a much more dramatic reaction in comparison (meaning the egg shrunk more and a lot faster).

[@DRONA_LIMIT]

Ok but how much do I pay someone to EAT those eggs? I need to know about flavor profiles. For science.

[@yosupbro1]

I NEED HELP>.< sorry... does the increase of salt in water decrease/increase the weight of an egg?? please help asap...

[@yosupbro1]

i already tried the experiment however the numbers had no correlation, and according to the internet, the numbers are meant to decease... So im confused, please help, as a student

[@XoletteScience]

yosupbro1 If you tried the experiment, then you should be able to answer your own question. In the salt solution, did your egg increase in size (water entered the egg) or decrease in size (water left the egg)? When you watch this video, does the egg increase in size or decrease in size when placed in a hypertonic solution? That is all you need to know to answer your question.

[@yosupbro1]

oh, so it decreases mass as more salt is added, due to the decreasing amount of water right? Although the egg did decrease in size for the hypertonic solution, i am still slighty confused. Salt water has a high concentration and osmosis is moving from a high concentration to a low concentration, so shouldnt the mass increase?? Im so confused. And i ont have enough time to repeat my experiment...

[@XoletteScience]

yosupbro1 You are correct in your first statement and I see why you're confused. My students do the same in that they confuse the definitions of diffusion and osmosis. First of all, solutions want to reach dynamic equilibrium (DQ)-- this means that the concentration of the solution wants to be equal everywhere. Diffusion is the movement of PARTICLES from a high to a low concentration to reach DQ (imagine dye particles moving and spreading out throughout a glass of water). Osmosis is the movement of water through a membrane to reach DQ. Why does water move instead of the particles? It's because the particles can't move through the membrane as these particles are too big. Water molecules are smaller and can pass through, so to reach DQ, the water has to pass through this membrane. Therefore, the water moves from a LOW concentration of solutes to a HIGH concentration of solutes. Think of the egg releasing it's water so it can water down the salt solution in order to reach DQ. The opposite happens if the egg is placed in pure water. Water moves INTO the egg to water down it's inner solution to match the concentration of the outside solution. You can think of osmosis as water molecules, that want to party so they head towards the crowded particle party. For diffusion, think of anti-social particles that just want to be spaced out and move away from the crowd. So overall, go over your definitions of diffusion and osmosis. It gets easy to mix up the two, especially when they use the same vocabulary. Good luck!
