A NaCl solution with a 266 mOsm will diffuse across into a Glucose solution with a 200 mOsm?

2006-09-12 04:55:23 · 3 answers · asked by Anonymous in Science & Mathematics Chemistry

The thing that confuses me is that 266 is higher than 200, but when measuring mOsm is it opposite? Meaning 200 to 1 ratio is more concentrated than 266 to 1? Am I thinking this out along the right lines?

Yes, the driving force for osmosis is the concentration gradient. Species that are permeable to the membrane will diffuse across the membrane to the side with lower concentration. This will be the case for many common lab procedures, such as dialysis.

One answer stated that the solvent does the moving and not the solute. This is only the case if the membrane is not permeable to the solute and is most commonly used in reverse osmosis

In osmosis, it is the solvent that does the moving. Net movement will be to where there is less solvent (higher amount of solute.)
