- what are indicators ? indicators are weak acids or weak bases that show a change in color as the concentration of Hydrogen ions in a solution changes or the pH of a solution changes. The indicators dissociate slightly in the water to form ions. Some examples of indicators are Litmus, turmeric, phenolphthalein, etc.significance of Universal indicators in food industryThe advantage of the universal indicator is that it displays a variety of colors over the whole pH scale. This makes it possible to determine an approximate pH of a solution over a range from 1-14.
