Understand the concept of osmosis: Osmosis is the movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the concentrations of the solutions: Solution A has a concentration of 6.78% NaCl, and Solution B has a concentration of 12.7% NaCl.
Determine the direction of solvent flow: Since osmosis causes the solvent to move from a lower concentration to a higher concentration, the solvent will move from Solution A to Solution B.
Predict the change in volume: As the solvent moves into Solution B, the volume of Solution B will increase, while the volume of Solution A will decrease.
Conclude which solution will increase in volume: Based on the principles of osmosis, Solution B will increase in volume because it has a higher concentration of NaCl compared to Solution A.
