Raw Data:
Table 1: Weights of potato pieces Solutions for the potato pieces to be dipped in(M) | Mass of potato pieces in Grams (+/-0.01)(initial mass) | Time when the potato pieces were dipped in the solution in seconds (+/- 0.01) | Time when the potato pieces were taken out of the solution in seconds(+/- 0.01) | Mass of potato after a hour in Grams (+/- 0.01) (final mass) | Water | 2.62 | 0 | 0 | 3.19 | 0.1 | 2.54 | 60 | 180 | 2.99 | 0.2 | 2.44 | 60 | 120 | 2.76 | 0.3 | 2.56 | 12 | 150 | 2.76 | 0.4 | 2.61 | 60 | 138 | 2.67 | 0.5 | 2.83 | 24 | 180 | 2.84 | 0.6 | 2.61 | 42 | 60 | 2.40 |
Qualitative Data:
Sucrose concentrations appeared to be colorless. Osmosis is is the net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration. Potato is made up of tiny cells and is protected by a cell membrane. Six solutions and water was taken to obtain the results of Osmosis. The potato pieces sank into the solutions. The change in the masses shows that osmosis occurred. Mostly there is a change in the mass of the potato when sank in the solution for about an hour.
Processed data:
