PROJECT TITLE
The Effect of Salt on the Boiling Temperature of Water

PURPOSE OF THE PROJECT
To find out how table salt affects the boiling temperature of water.

HYPOTHESIS
Adding table salt to boiling water will cause the water to boil at a higher temperature.

MATERIALS AND EQUIPMENT
Table Salt
Distilled Water
2 Quart Cooking Pot
Measuring cup
Teaspoon and tablespoon
Thermometer
Stirring spoon

EXPERIMENTAL PROCEDURE
1.Boil one quart of distilled water on a stove.
2.Measure the temperature of the boiling water. Record the highest temperature reading.
3.Measure out table salt using a kitchen measuring spoon. Level the spoonful.
4.Add the measured salt to the boiling water and stir.
5.Measure the temperature of the boiling water with the salt in it. Record the highest
temperature reading.
6.Repeat for other amounts of salt.

DATA
Amount of boiling water
2 Cups
Temperature of boiling water (Control)
212.9° F
Amount of table salt added to boiling water: Run #1
1 Tbl.
Temperature of boiling water after adding salt: Run #1
216° F
Additional amount of table salt added to boiling water: Run #2
1 Tbl.
Temperature of boiling water after adding salt: Run #2
218° F



OBSERVATIONS
When the salt was added to boiling water it bubbled up more, and then stopped boiling.
Shortly afterwards, it boiled again. If the thermometer extends beyond the outside of the
pot it reads a higher temperature. Heat from the stove burner makes the thermometer read
higher. I had to keep the thermometer over the pot when m...
