Osmosis Lab Report
Data Collection:
The aim of this experiment was to test the weight of six potatoes before and after being put into different sucrose solutions. The following data was observed and collected throughout the experiment.
Observations:
-Qualitative:
The potatoes were:
Tubed shaped
Yellow in color
Initially hard in texture
-Quantitative:

We only had the potatoes in their solutions for 20 minutes instead of the normal 30 minutes which could mean that the potatoes did not go through the whole process of osmosis. Also, a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself, and so next time we could do a lab under normal conditions where there are no outside disturbances.
There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same weight for all the six potato tubers as it would have been very time consuming to do so. Next time I would suggest that the potato tubers be already prepared for us, each with a similar initial weight.
The sucrose solutions were left open so things could have fallen in and caused problems by decreasing sucrose molar levels. In the next experiment, there should be lids on the sucrose solutions so that no dirt or dust could contaminate the
