The color of the dye comes from the delocalization of electrons in the πbonding system (Exton‚ 149). Bleach is an aqueous solution that contains sodium hypochlorite (NaOCl). The hypochlorite of bleach breaks the double bonds of the food dye through oxidation‚ forming molecules that do not absorb visible light and thus bleaching the product

description of how two dyes are separated when a solution of the dyes is passed through a column of powdered silica contained in a vertical glass tube‚ it’s a method used to separate solids or liquids. At the first the two dyes are adsorbed at the top of the column‚ giving this region a nearly dark blue color. However‚ when the flow of solution is discontinued and pure solvent is allowed to flow through the column‚ the process known as development occurs. The greenish dye is held tenaciously at
