This project investigates the effect of salt on the boiling point of water. Students will measure the boiling points of pure water and saltwater to understand how solutes affect boiling temperatures.
Adding salt to water will increase its boiling point compared to pure water.

Measure 1 liter of distilled water and pour it into the pot.
Place the pot on the heat source.
Insert the thermometer into the water, ensuring it does not touch the pot's bottom.
Heat the water and record the temperature at which it boils.
Remove the water from heat and let it cool.
Add 100 grams of table salt to the water and stir until dissolved.
Repeat the boiling process with the saltwater solution, recording the boiling temperature.
Compare the boiling points of pure water and saltwater.
Analyze the results to draw conclusions.
The boiling point of saltwater is higher than that of pure water, demonstrating the impact of solutes on boiling temperature.
Amount of salt added

Use caution when handling hot water and heat sources. Avoid direct contact with the hot pot.
Create a clear visual graph comparing boiling points.
Include photos or videos of the experiment.
Prepare a summary sheet of findings.
Explain the scientific principles behind the results.
Salt increases the boiling point due to the colligative properties of solutions.
Yes, other solutes like sugar can also be tested for their boiling point effects.
Understanding boiling point elevation helps in cooking and various industrial processes.
