4. Na\'Ch movement when testing the 100 MWCO membrane reached equilibrium in 10

Question

4. Na'Ch movement when testing the 100 MWCO membrane reached equilibrium in 10 minutes. This is due to: a. Pore size within the 100 MWCO membrane b. The amount of Na*Cl in the first beaker (9.0 mM) c. Smaller membranes influence diffusion rates d. Movement down a concentration gradient leads to solute balance between beakers In osmosis, water moves from a higher concentration of water to a lower concentration of water. Also contributing to this movement of water is: a. A low concentration of solutes on one side of a water permeable membrane b. A high concentration of CO2 on one side of a water permeable membrane c. A high concentration of solutes on one side of a water permeable membrane d. A low concentration of CO2 on one side of a water permeable membrane e. The movement of water is only affected by water concentrations; solutes do not 4. contribute to water movement

Explanation / Answer

4. a. Pore size is within 100 MWCO membrane. That is why Na+cl- movement was so fast.

5. e. The movement of water is only affected by water concentrations , solutes do not contribute to water movement. Osmosis is a process where water moves from a higher concentration of water to lower concentration of water when differentiated by a semi permeable membrane. It does not depend on the solutes.
