A and B are solutions of salt dissolved in water that are separated from each other by a semipermeable membrane in each scenario
. Water can pass through this membrane, but the salt cannot. Match each pair of solutions to the net direction the water will flow between the two solutions. Net flow toward solution A Net flow toward solution B No net flow
solution A: 14% salt solution solution B: 1% salt solution solution A: 5% salt solution
solution B: 5% salt solution solution A: 4% salt solution solution B: 13% salt solution
<u>solution A: 14% salt solution solution B: 1% salt solution:</u> net flow towards solution A.
<u>solution A: 5% salt solution solution B</u>: 5% salt solution: no net flow
<u>solution A: 4% salt solution solution B</u>: 13% salt solution: net flow towards solution B.
Explanation:
<em>This is a simple case of osmosis - the movement of water molecules of the region of lower concentration of solute to the region of higher concentration of solute through a permeable membrane. </em>
The net movement of water will always be towards the solution with higher salt concentration. Hence;
<u>solution A: 14% salt solution solution B: 1% salt solution:</u> net movement of water would be towards solution A.
<u>solution A: 5% salt solution solution B</u>: 5% salt solution: no net movement
<u>solution A: 4% salt solution solution B</u>: 13% salt solution: net movement of water would be towards solution B.
