Final Steps and Mass Measurement in Osmosis Experiment

This section details the final steps and mass measurement for the potato osmosis experiment method.

Experiment procedure:

1. Place each potato chip into its respective beaker with sucrose solution.
2. Leave the chips in the solution for 2 hours.

Final mass measurement:

1. Remove potato chips using forceps.
2. Blot dry each chip on paper towel.
3. Measure and record the final mass of each potato chip.
4. Fill in the data in the "Final potato mass (g)" column of the results table.

Highlight: Use a stopwatch to accurately time the 2-hour soaking period.

Example: The potato osmosis experiment observations will show how different sucrose concentrations affect the final mass of the potato chips due to osmosis.

Osmosis Required Practical: Investigating Osmosis in Potato Chips

This practical guide outlines the steps for conducting an osmosis experiment with potato chips to investigate how solution concentration affects the change in mass due to osmosis.

Key points:

• Aim: Investigate how sucrose solution concentration affects potato chip mass change
• Hypothesis: Potato chip mass will decrease as sucrose concentration increases
• Independent variable: Sucrose solution concentration (0%, 40%, 80%, 100%)
• Dependent variable: Percentage change in potato chip mass
• Controlled variables: Potato chip size, time in solution, solution volume

Highlight: Safety precautions include not consuming any solutions or potato chips and taking care when cutting potatoes.

Vocabulary: Osmosis - The movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.
