NettetOsmosis- Evaluation + Conclusion. In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water, one was 5% sugar, one 10%, one 15%, one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution.
