Acid Effects on Teeth

Lab Summary

Use a pH sensor as a means of quantitatively describing the acidity of various beverages.

Theory

Students use the pH scale to quantitatively describe how acidic a substance is and they connect the acidity of common beverages to the need for brushing one’s teeth.

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the pH of several different liquids
  • Measuring the pH of vinegar, orange juice, and a variety of soda pop beverages.

Sensors / Equipment Used:

PASPORT Chemistry Sensor

(PS-2170)

Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
