Materials Required:, Sugar and salt solutions phet worksheet answer key
- Sugar
- Salt
- Water
- Measuring cups and spoons
- Clear glass or plastic cups
- Hydrometer
Experimental Procedures
- Prepare three clear cups labeled “Sugar Solution,” “Salt Solution,” and “Control.”
- In the “Sugar Solution” cup, dissolve 10 grams of sugar in 100 milliliters of water.
- In the “Salt Solution” cup, dissolve 10 grams of salt in 100 milliliters of water.
- Leave the “Control” cup with only water.
- Stir each solution thoroughly until all the solute is dissolved.
- Measure the density of each solution using the hydrometer.
- Record the density measurements in a data table.
- Observe and compare the appearance of the three solutions.
Data Collection and Analysis
Collect the density measurements for each solution and record them in a data table. Analyze the data to determine the following:
- Which solution has the highest density?
- Which solution has the lowest density?
- How does the density of the sugar solution compare to the density of the salt solution?
- How does the density of the control solution compare to the density of the sugar and salt solutions?
Discussion and Conclusion
The results of the experiment will show that the sugar solution has a higher density than the salt solution, and both solutions have a higher density than the control solution. This is because sugar and salt molecules are denser than water molecules, so when they are dissolved in water, the overall density of the solution increases.
The experiment also demonstrates the concept of solubility. Sugar and salt are both soluble in water, meaning they can dissolve and form a homogeneous solution. However, the solubility of sugar is higher than the solubility of salt, so more sugar can be dissolved in water before the solution becomes saturated.
