Acid-Base Properties of Household Products
Recommended for grades 9–16.
Introduction
Many common household solutions contain acids and bases. The acidity of a solution can be expressed using the pH scale. Acidic solutions have pH values less than 7, basic solutions have pH values greater than 7, and neutral solutions have pH equal to 7.
Objectives
In the Preliminary Activity, you will gain experience using a pH Sensor as you measure the pH of three solutions: baking soda, milk, and a soft drink. You will then classify the three solutions as acidic, basic, or neutral.
After completing the Preliminary Activity, you will first use reference sources to find out more about household acids and bases and their chemistry before you choose and investigate a researchable question.
Sensors and Equipment
This investigation requires each of the following Vernier sensors and equipment (unless otherwise noted):
Additional Requirements
You may also need an interface and software for data collection. What do I need for data collection?
Download Experiment Preview
The student-version preview includes:
- Step-by-step instructions for the Preliminary Activity
- List of materials and equipment
Note: The experiment preview of the Preliminary Activity does not include essential teacher information, safety tips, or sample data. Instructions for Logger Pro and other software (such as LabQuest App or TI handheld software, where available) are on the CD that accompanies the book. We strongly recommend that you purchase the book before performing experiments.
