Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.
