EXPERIMENT 3: OSMOSIS – DIRECTION AND CONCENTRATION GRADIENTS Data Sheet Table 6: Sucrose Concentration vs. Tubing Permeability Band Color Sucrose % Initial Volume (mL) Final Volume (mL) Net Displacement (mL) Yellow 3 % 10 mL 15 mL 5 mL Red 3% 10 mL 12 mL 2 mL Blue 3% 10 mL 9.6 mL .4 mL Green 30 % 10 mL 6 mL 4 mL Post-Lab Questions 1. For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, or isotonic in comparison to the beaker solution it was placed in. Yellow solution was hypotonic compared to the solution of beaker #2. Red solution was also hypotonic compared to the solution of beaker #2. Blue solution was isotonic compared to the solution of beaker #2. Green solution was hypertonic compared to the solution of beaker #1. The pieces ranched from 30% hypertonic compared to hypotonic, 15% hypertonic compared to hypotonic, 3% isotonic compared to isotonic, and 3% hypotonic compared to hypertonic solution.
