Course Hero Question - Which substance(s) crossed the dialysis membrane and moved into the beaker solution?
Criteria – No word limit and no page requirement; don’t forget to mention what evidence from your results proves this.
1. Dialysis bag solution consists of 5ml of glucose solution and 5ml of starch solution; minus 2ml mixture of both for the control point.
2. Beaker 4 solution first consisted of the 2ml mixture of the glucose and starch solution; then added a few drops of IKI solution.
3. Beaker 2 solution first consisted of 80mil of water; then added the dialysis bag of mixed starch and glucose solutions to sit in; then added 2ml of the IKI solution to the 80ml of water.
4. In tables 4 & 5, I know the initial colors are correct, not sure of the final colors.
