Is it an Acid, Base, or Neutral?
Learning Outcomes1. Classify common substances as acid, base, or neutral by observing reactions with an indicator.
2. Design and conduct an inquiry to determine what happens to an indictor when various amounts of acids and bases are mixed. 3. Construct word equations for neutralization reactions. 4. Analyze data from an inquiry to determine how the concentration of an acid or base affects a neutralization reaction. ActivitiesTennessee Holt Science and Technology, Chapter 14 .
