Which substan ce(s) were present in the water inside the dialysis bag at the end of the experiment? 4)

Answer 1

L. Glucose was present in the water outside the dialyst's bag at the beginning of experiment. 2. chloride and outside the glucose were present in the watee. dialysis bag. after 25 min. dialysis bag after 30 min 4. Chloeides was present in the water enside the dialysis bag at the end of experiment. chlorides were able to dialysis bag by passing membrane diffuse out of the through the semipermeable Glucose i able to diffuse into the bag dialysis bag through semipermeable membrane. starch was unable to pass through membrane of the dialysis bag. gemipermeable
