What are the variables in the potato osmosis lab?
Each row in this tidy dataset contains an observation for a single potato piece. Each column in the dataset is a variable and the cells in that column are the values of that variable. The variables recorded for each potato piece are Lab Group Name, Sucrose Concentration (Molarity), Initial Mass (g), Final Mass (g), and Mass Change (%).
How to measure salt concentration in potato cells?
Weigh all potato cubes individually and record data. Place 50 ml distilled water in a beaker. Place the 2 potato cubes in the distilled water. Leave for 20 minutes. Use a spoon to carefully remove the 2 potato cubes from the beaker and place them on a piece of paper towel to remove excess water. Record any visual observations in your table.
How are the dimensions and mass of potato cubes kept similar?
The dimensions and mass were kept similar by using a ruler to adjust the dimensions of the potato cubes and weighing them all to ensure a similar mass. If the volume of salt solution is different in the four beakers, then there will be more/less water to transport by osmosis.
Why is distilled water hypotonic to potato cells?
The distilled water was hypotonic compared to the potato cells that contain approximately 2% salt. Hence why both the individual and class data indicated a gain in the potato mass.
