pH Scale: Basics
About
Topics
- pH
- Acids
- Bases
- Dilution
Description
Test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Investigate how adding more of a liquid or diluting with water affects pH.
Sample Learning Goals
- Determine if a solution is acidic, basic or neutral
- Place acids or bases in order of relative acidity or basicity
- Relate liquid color to pH
- Predict how solution volume or dilution with water will affect the pH of acids or bases
