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