Objective
Examine the effect of temperature on the solubility of various substances in water.
Materials
- Sugar
- Salt
- Baking soda
- Water
- Beakers
- Stirring rod
- Thermometer
- Hot plate
- Notebook for observations
Instructions
- Measure a specific amount of water into a beaker and record its temperature.
- Add a small amount of sugar to the water and stir until it dissolves.
- Continue adding sugar incrementally until no more dissolves, and record the amount added.
- Repeat the procedure at different temperatures using a hot plate to warm the water.
- Repeat the entire experiment with salt and baking soda.
- Record the solubility of each substance at different temperatures in the notebook.
- Analyze the data to understand how temperature affects solubility.
