Experiment: Determination of Fluoride in Toothpaste
Significance:
Fluoride is an essential element for maintaining dental health. Its presence in toothpaste helps prevent cavities by strengthening the tooth enamel. However, excessive fluoride can be harmful to the body. This experiment demonstrates the application of analytical chemistry in the quality control of toothpaste production, ensuring that the fluoride content is within safe limits.
Materials:
- Toothpaste sample
- Graduated cylinder
- Funnel
- Filter paper
- Burette
- Fluoride standard solution
- Sodium hydroxide solution
- Phenolphthalein indicator
Procedure:
- Weigh approximately 1 gram of toothpaste into a graduated cylinder.
- Add 100 mL of distilled water and mix thoroughly.
- Filter the solution through a funnel lined with filter paper.
- Pipette 25 mL of the filtrate into a flask.
- Add 2 drops of phenolphthalein indicator to the flask.
- Fill the burette with sodium hydroxide solution.
- Titrate the filtrate slowly, adding the sodium hydroxide solution until the solution turns a faint pink color.
- Record the volume of sodium hydroxide solution used.
- Repeat steps 4-8 with a known volume of fluoride standard solution to determine the molarity of the sodium hydroxide solution.
Calculations:
The concentration of fluoride in the toothpaste sample can be calculated using the following formula:
Concentration of fluoride = (Volume of NaOH used x Molarity of NaOH) / (Volume of filtrate x Mass of toothpaste)
Significance:
This experiment demonstrates the application of analytical chemistry in the quality control of toothpaste production. By analyzing the fluoride content, manufacturers can ensure that their products meet safety standards and provide optimal dental health benefits.
