| Hot plate | 1 | [Description of the hot plate] | [Image of a hot plate] |
Procedure
- Prepare solutions of different concentrations.
- Measure the boiling point of each solution.
- Plot the data on a graph.
- Analyze the data to determine the relationship between the concentration of a solution and its boiling point.
Safety precautions:
- Wear safety goggles when working with hot liquids.
- Do not touch the hot plate or the boiling solutions.
- Allow the solutions to cool before disposing of them.
Data Collection
Record the following data in a table:
- Concentration of the solution
- Boiling point of the solution
| Concentration of the solution (M) | Boiling point of the solution (°C) |
|---|---|
| [Concentration 1] | [Boiling point 1] |
| [Concentration 2] | [Boiling point 2] |
| [Concentration 3] | [Boiling point 3] |
Data Analysis
The data can be analyzed using a variety of statistical tests, including:
- Linear regression
- Correlation analysis
- Analysis of variance (ANOVA)
Discussion
The expected results of this experiment are that the boiling point of a solution will increase as the concentration of the solution increases. This is because the presence of more solute particles in the solution raises the vapor pressure of the solvent, making it more difficult for the solvent molecules to escape from the liquid and turn into gas.
Potential sources of error in this experiment include:
- Inaccurate measurement of the concentration of the solutions
- Inaccurate measurement of the boiling point of the solutions
- Evaporation of the solutions during the experiment
