Introduction to pH Measurement
kit #80
This series of simple, highly visual laboratory tests introduce students to the concept of pH. Students add drops of acid and base to a variety of pH indicators and observe how pH indicators can detect and differentiate acids and bases. Students are also introduced to the concept that acid and base discussions are not limited to chemistry but also extend to applications in biology and the study of the human body.
- pH indicators can detect and differentiate acids and bases.
- The pH scale is a method of measuring the relative strength of acids and bases.
