ABSTRACT
Natural dyes are living chemical compound which showed color in presence of oxygen and color less in presence of hydrogen. The addition of oxygen and hydrogen results in an oxidation and reduction of dye. This change in color was used for the demonstration of oxidation and reduction visually in one day open activity of chemical show of oxidation reduction reaction where students gain knowledge very easily about the oxidation and reduction reaction just by showing the change in color of reaction mixture.
