Certain dyes change colour depending on whether they are in an acid solution or an alkaline solution .

In this video we will learn about pH indicators and how they work including but not limited to litmus paper and red cabbage indicator. The pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +). Normally, the indicator causes the colour of the solution to change depending on the pH. Typical indicators are phenolphthalein, methyl orange, methyl red, bromothymol blue, and thymol blue. PH Indicators works as halochromic chemical compound which when added to solution in small amounts allows determination of pH. With the possibility of determining it visually, it results in color of solution to change depending on pH. pH indicators made from edible substances.
