Soap Dissintegration

...

are small pockets of air in the bar of soap which may cause for faster dissolving.

Materials

1. Two different bar soaps (Lever 2000 and Dial Original)

2. A kitchen knife

3. An emptied plastic water bottle

4. Tap water (0.8 liters)

5. Hard surface to cut bar soaps

6. Measuring cup

7. Colander

8. Scale

9. Thermometer

Procedure

1. Gather all materials

2. Make sure the hard surface is clean

3. Grab knife (hold away from yourself) and cut out one 5cm by 5cm sized cube from one bar of soap

4. Measure temperature of the water with the thermometer in Celsius

5. If right temperature 26.1℃, measure 200ml of water and pour into the plastic water bottle

6. Weigh the cube of soap before you put it in the bottle

7. Put one cube of soap in the water bottle

8. Shake consistently for one minute and thirty seconds; to control how much you shake the bottle place a ruler vertically (up and down)

9. Pour water and soap contents in the colander

10. Take cube off colander and weigh the cube of soap (after it is dry) and measure the size with a ruler (measure in centimeters)

12. Record data

13. Repeat steps 2-11 twenty times for each bar soap (only two types of soap)

Variables

The independent variable in this experiment is the different types of bar soap. The dependent variable is the soap that dissolved the fastest in water. The controlled variables are the amount of water in the bottles, the temperature of the water, the size of the cubes of soap, and how much you shake the bottle.

Results

During this experiment, the results do not vary much in weight. When I was shaking the bottle, there was a lot of soap foam. The foam filled up the bottle, other than the water that was already there. When I took the soap cubes out, I had to let them dry for a while because the soap cube soaks up water. The soap cube will be heavier than the beginning if you weigh it without letting it dry.

Conclusion

Ivory bar soap dissolves the most in water. Six of the ten tests for Ivory were all 1/8 ounces which means more of the cubes dissolved. For Lever 2000 five of the ten tests were 1/8 ounces which means that only half of the ten tests dissolved. My hypothesis was supported because Ivory soap dissolved more than Lever 2000.
