Question

1. Based on the initial concentrations of water inside and outside the dialysis tubing, what can you conclude about the direction of osmosis? Explain.
2. what can you conclude about:
   1. The dialysis of glucose?
3. 2. The dialysis of starch?

Answer 1

In this case, it will depends on the concentration of water inside and outside the dialysis tubing at the beginning of the experiment. Remember that water will flow from the less concentrated side of solute to the most concentrated side of solute.

In both cases (glucose and starch) this statement will be applied. So, you need to observe your results. If the dialysis tubing lost water, the outside was much more concentrated that the inside of the tube. If the dialysis tube gained water, the dialysis tube was more concentrated that the outside.
