摘要
利用安卓智能手机的CMOS传感器并配合安卓手机软件ColorGrab来获取不同编号试管中FeCl3溶液的L＊，a＊，b＊值，并将相应数据导入到智能手机的WPSOffice中处理后得到相应的色差值，通过比较色差值大小来探究浓度对化学平衡的影响，取得了良好的效果。
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 corre- sponding 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.
