pH Pre-Lab: Acids and Bases
In this chemistry lab, students determine whether or not their saliva is acidic, basic, or neutral. After completing their test, they answer 6 analysis questions.
Curated OER
Observing Buffers In Lakes, Ponds And Streams
Young scholars observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.

HOW IS PH DETERMINED?
Learners estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.
