Introduction to Acids and Bases
Use a pH sensor to measure the pH of several different household chemicals
Working with common household chemicals, students develop an understanding of the pH scale. In this activity, students investigate and observe how red cabbage juice changes color in the presence of acids and bases and relate this visual indicator to the numbers of the pH scale.
Additionally, students will be able to:
Recognize that substances often are placed in categories or groups if they react in similar ways, such as an acid or base
Make explanations and predictions from evidence and drawing logical conclusions
Gain skills and confidence in using a scientific measurement tool—the pH sensor—as well as the spreadsheet and graphing capability of a computer to represent and analyze data
Students gain experience conducting the following procedures:
- Setting up the equipment and work area to measure the pH of different household chemicals
- Measuring the pH of several different household chemicals
- Classifying chemicals as acid, neutral, or base
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
