Question

A) The important factor in osmosis is not the number of molecules. Instead, it is the number of particles in a given volume of solution. For example, one glucose molecule dissolved in water yields one particle, but one NaCl molecule can yield two ions: Na+ and Cl-. Water moves osmotically in response to the total concentration of particles in the solution.

If there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water? (1 point)

Answer 1

Since the salt has two ions, the concentration of particles is double the salt concentration (10%). Since it is equal to the glucose concentration, water will not flow to either side of the membrane.
