Acids and Bases
Lemon juice or soapy water? You can't tell by looking — but add a drop of 🧪 cabbage indicator and watch the color change! Red for acid, purple for neutral, and blue-green for base. Watch two litmus papers change too! Slide the pH control from 0 to 14 to see a rainbow of colors, then take the color-guessing challenge. Experiment with 9 solutions! Supports 7 languages.
