Lab-Aids: Introduction to pH Measurement Kit - Bilingual English/Spanish
This series of simple, highly visual lab activities introduce students to the effects of acids and bases on litmus indicators, indicator solutions, and natural indicators. The activities begin by discussing the differences between acids and bases. It then moves to a discussion on the use of pH test paper and the interpretation of their results. 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. The lab activity uses LAB-AIDS‚® Chemplates‚® to study side by side, the reaction of Hydrochloric Acid and Sodium Hydroxide when mixed with other liquids and on pH paper. Lab is complete for 50 students.
