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
