Abstract This paper got the values of L*, a*, b* of FeCl3 solutions in different test tubes by using CMOS sensor and software Color Grab of Android smart phone, and imported corresponding data to WPS Office to get the corresponding value of chromatism, then studied the effects of concentration on chemical equilibrium through the comparison of value of chromatism, good results had been achieved.
