Question

If you were to place 2 M of MgCl₂ into a dialysis sac and then place that dialysis sac into a beaker of 2 M solution of glucose, what would happen to the dialysis sac?

Answer 1

When 2 M of MgCl₂ is placed into a dialysis sac and then placed into a beaker of 2 M glucose solution, the glucose molecules would diffuse through the dialysis bag, while the MgCl₂ molecules would not. Water molecules might also move in or out of the dialysis sac.

Step-by-step explanation:

When 2 M of MgCl₂ is placed into a dialysis sac and then placed into a beaker of 2 M glucose solution, several things happen to the dialysis sac:

1. The glucose molecules (monosaccharide) would diffuse through the dialysis bag into the surrounding solution because they are smaller and can pass through the membrane.
2. The MgCl₂ molecules (ionic compound) would not be able to diffuse through the dialysis bag due to their larger size and charge.
3. The water molecules might also move in or out of the dialysis sac, depending on the concentration of solutes on either side of the membrane.
