Universal indicator. Universal indicator changes its colour depending on the pH of the solution. Here universal indicator has been added to three beakers containing solutions with varying pH values, front to back: alkaline (blue, pH=12, 0.01M potassium hydroxide, KOH), neutral (green, pH=7 buffer solution), acidic (red, pH=2, 0.01M hydrochloric acid, HCl). | |
