Design 2.1 Focus Question: What is the effect of different concentrations of salt solutions surrounding potato cells, Solanum tuberosum have on the osmosis of such cells. Hypothesis: If a 1 cm cube of Solanum tuberosum is covered with a high 40% concentration of sodium solution then the mass of Solanum tuberosum will decrease due to osmosis. However, when covered with distilled
