Universal indicator acid colour range. Footage of the acid colour range of universal indicator solution demonstrated in flasks containing liquids of different pH values. The acid-base (pH) scale runs from 0 to 14. The flasks here mostly contain acidic liquids. The colours and approximate pH values are, from left to right: red (pH 1), orange (pH 3), yellow (pH 5), light green (pH 7, neutral) and dark green (pH 9). For the full ranges of colours, see clip K005/3824. | |
