Molecular formula :
nature : precipitation titration by the indicator. Most of organic dye in the solution free of the color and anions were charged precipitation particles adsorption of different colors. When the other point, the indicator in the adsorption or desorption make it happen color change, which may direct the destination. As with silver nitrate (AgNO3) titration of sodium chloride (NaCl) solution can be used for fluorescent yellow indicator, such as when to titration points, slightly excessive precipitation Ag + with positive electricity and adsorption into red and yellow fluorescence was observed by yellowing Solution Hung reached the end.
