indicator
Molecular formula :
MW :
CAS :

nature : a chemical reagent category. Due to the nature of certain changes or because some compounds in the presence of the color change their material. Mainly for titration analysis instructions titration end. The general can be divided into acid-base indicator, redox indicator, the indicator adsorption, and other metal indicator. In addition, there are common indicator indicator within and outside indicator of such terms. Indicator addition to the analytical chemistry for the operation of signal, sometimes used directly test solution gas or certain harmful, toxic substances exist. For example, silica gel adsorption in the lead-acid solution, encountered air containing hydrogen sulfide, that is, changing from white to brown.
