6. Imagine the experiment below where you placed a dialysis tube (cell) containing 10% NaCl Solution A Dialysis Tube Solution B (solution B) into a beaker of distilled water (solution A). Using what you know about diffusion/osmosis, indicate if the water is going to move into or out of the dialysis 'cell’.

Transcribed Image Text:9. Using the images of blood from 7.8 in the lab manual, what
is the ideal tonicity of sheep's blood? Explain.
10. Using the image in 7.9 of the Elodea cell tissue in the lab
manual, why is a hypertonic environment dangerous to
plant cells? Explain.
11. Review the following experiment and answer the
questions.
You set up an experiment where you place a sealed
(clamped) dialysis tube cell in a beaker of water. The
solution in the dialysis tube cell is 25%NaCl solution and
the solution in the beaker is 1%NaCl solution. The solvent
for both is water.
Before you place the tube in the cell, after it has been filled
and clamped, you find the mass of the cell. You also find
the mass of the cell after it has been placed in the beaker
solution for 30 minutes. The masses are in the table below.
Mass in grams of dialysis tube cell
Initial Mass
25g
Final Mass after 30 minutes 28.7g
Using this information, explain the difference in mass
before and after submerging the cell in the beaker solution.
Explain.
