India is the country of colourful flowers. People use the colorful flowers for their ornamental use and also for their medicinal uses since ancient time. The method of wet chemistry such as titrimetric analysis and gravimetry still has an important role in modern analytical chemistry. There are many areas in which titrimetric procedures are invaluable. Almost any highly colored fruit or vegetable or flower petal has the potential for use as an acid base indicator. Acid-base indicators are commonly employed to mark the end of an acid-base titration or to measure the existing pH of a solution.
