Osmotic pressure is defined as MRT (or concentration*gas constant*temperature). Just remember that water will go from low solute concentrations to high solute concentrations. Or, analogously using the equation above, water will go from low MRT to high MRT.water potential, osmotic potential, and osmotic pressure? also, is there such a thing as water pressure?
everywhere i look on the internet I get conflicting results. Is this concept poorly defined?
Yes, the first one is right. About the second question, are you getting the negative number because of -MRTi (concentration*gas constant*temperature*van't Hoff factor)? It seems from this that yes, the highest possible water potential is zero, and for this number to become more negative means to have more solute concentration M. So the more negative this gets, the lower the water potential but the higher the osmotic potential. You can also just use MRT, where the greater this number gets, the same thing happens: the lower the water potential and the higher the osmotic potential.so if something has a high osmotic pressure, is has a high osmotic potential, and if something has a high hydrostatic pressure, it has a high water potential?
and when I say high water potential, I mean zero, because if there's a solute in it, water potential is NEGATIVE. right?
Hydrostatic pressure = pushes things out.Hi!
I was just reading over this section in EK and im slightly confused what is the difference between water and osmotic potential in a sense of moving solution across a membrane
