Maryjane Taylor · Answer 1

The answer would be to the 34% NaCl solution

Osmosis happens when there is a difference in the osmotic pressure. Osmotic pressure will be influenced by how many ions a molecule made in water. NaCl will make two ions, Na + and Cl-. A glucose won't make ions. In this question, the NaCl concentration is 34%, already bigger than the 22% glucose. The net osmosis pressure for the NaCl would be bigger since it makes 2 ions. So the water definitely going to the NaCl solution

Yasmine York · Answer 2

The net osmosis will occur in the direction of the NaCl solution. This is because the solute concentration on that side is greater than that of the glucose solution. Osmosis is the process by which liquids move through semi permeable membrane from the region of lower concentration to the region of higher concentration.

Thus the water is going to move from the glucose solution into the NaCl solution.
