Drop cabbage indicator into solutions and slide the pH to see how acids, neutrals, and bases each change color.
About this app
Acids and Bases is an interactive science learning app for exploring how red cabbage indicator colors change in acidic, neutral, and basic liquids. Choose liquids such as lemon juice, vinegar, water, salt water, baking soda water, soapy water, glass cleaner, and limewater, then add the indicator to observe the result. A pH slider explains strength from 0 to 14, while a color-based quiz provides practice with scoring and streaks.
