1. pH Indicator

2. Why? and Observations  To check if the substance was acidic, neutral or basic  Different liquids changed different colors based on the pH  Lemon juice: pH: 2.25 color : light pink most acidic  Borax: pH : 9.43 color : light purple most basic

3. What we learned We learned how to test the acidity of different types of liquid using red cabbage juice as a pH detector We learned that the universal indicator says that red is the most acidic and the purple shade is the most basic
