Why does osmosis happens?
Does osmosis happens when we have osmotic pressure difference between the two solutions (that are connected by a membrane)?
Does osmosis happens when we have two solutions of different concentrations?
My professor told that osmosis happens because of the vapour pressure difference between the solutions. But I didn't understand what vapour pressure has to do with osmosis. Can you explain me that, please?
I've been thinking too and is the vapour pressure of a solution numerically equal to the osmotic pressure of that solution? I see this relation because I know the more concentred is the solution the bigger is it's vapour pressure... that's right?
How do I calculate vapour pressure? (Can I use p V = n R T?)
Does density of the solutions has anything to do with osmosis? And what about hidrostatic pressure?
Thank you for the help,
