The paper elaborates the features and superiority of applying multimedia technology to chemistry experiment instruction in details, and introduces the practical application of multimedia technology in demonstration experiment. The application of multimedia technology in chemistry experimental instruction has its own features, namely enjoyment, great information capacity, sharing network, easy operation and flexibility. The paper concludes the superiority of applying multimedia technology to the chemistry experiment instruction from nine perspectives. Meanwhile, the paper elaborates its disadvantages. Simulated experiments cannot take place of real experiments. The relationship among teachers, students and multimedia needs to be dealt with properly, and the multimedia courseware should be scientific. Prospective forecast of multimedia technology in chemistry experimental instruction is also demonstrated.
