A semipermeable membrane is placed between the following solutions.
Which solution will increase in volume?
A
Solution A:6.78% NaCl
B
Solution B:12.7% NaCl
Verified step by step guidance1
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.
Compare the concentrations: Solution B has a higher concentration of NaCl compared to Solution A.
Predict the direction of solvent movement: Since osmosis moves solvent from lower to higher solute concentration, the solvent will move from Solution A to Solution B.
Determine which solution will increase in volume: As the solvent moves into Solution B, its volume will increase.
