Part I: Dialysis bags ("cells") are placed in three different beakers. The cells, as well as the beakers, contain different aqueous solutions of NaCl. For each of the beakers, answer the questions below.
Beaker #1
Beaker #2
Beaker #3
Cell # 1
Cell # 2
Cell # 3
Cell # 1 contains 15% NaCl
Beaker contains 35% NaCl
Cell # 1 contains 30% NaCl
Beaker contains 30% NaCl
Cell # 1 contains 50% NaCl
Beaker contains 25% NaCl
Beaker #1:
a) The solution inside the cell contains 15% NaCl and % water.
b) The beaker contains 35% NaCl and % water.
c) The solution inside cell #1 is tonic to the solution outside cell #1.
d) The solution outside cell #1 is tonic to the solution inside cell #1.
e) In which direction will water move? (circle one below)
Into the cell
Out of the cell
No net movement of water
f) Draw an arrow or arrows on Beaker #1 above to show the movement of water.
g) Explain how you determined the movement of water.
h) Over time, what will happen to cell #1? (circle one below)
Shrinks
Swells
Remains the same size
