Red cabbage indicator

Red Cabbage Indicator to Classify Liquids into Acids and Bases

An indicator reveals if a substance is acidic or basic. In solutions, acidic components release hydrogen ions, while basic ones release hydroxide (OH−) ions. The indicator changes color according to the solution’s nature. Materials Needed • Red cabbage• Knife (Use only under adult supervision; preferably let the adult do the chopping)• Blender• Strainer• Bowl• Clear …
