Abstract This paper studied the effect of reactant concentration on the chemical reaction rate using digital imaging colorimetric method, and the curve of "green (the complementary of light fuchsia solution) channel values"-time characterized the relationship between concentration and chemical reaction rate. Meanwhile, the relationship between the concentration and reaction rate was also inquired by the curve of "transmittance-time" using the spectrophotometer. The results indicated that digital imaging was a very simple and feasible way. In addition,using carry-on electronic products to carry on experiment research was interesting and scientific for the experimental teaching.
