Why is it when you increase the concentration of NaCl, the osmotic pressure of a solution increases? why does it has this effect?

my prediction is the more impermeable the solute, the higher the osmotic pressure will be, thus explaining why the osmotic pressured increased, when the concentrated of NaCl increased when i did the lab simulator. True?

Increasing the number of non-diffusible particles increases osmotic pressure. If solutes are able to diffuse, then equilibrium will be established and osmotic pressure will not be generated. Osmotic pressure would be zero if albumin concentration was the same on both sides of the membrane.

This is from PhysioEx 8, I'm assuming PhysioEx 9 is the latest edition, I gotta get on that Smile

yeah, it's latest version. Thanks for your input!

Also, what does it mean by " water chases milliosmoles?

Think, "water chases osmoles" to visualize which direction the water flows. Each osmole displaces approximately 1 mole of water.

No instructors guide exists for this version, I think.

Edit: it will be available in 5 days! Smile

so, I'm trying to comprehend what you said,"Water chases milliosmoles." It means to visualize which way water flows. Can you explain it in further detail for me? I'm having a hard time comprehending it
