Abstract The electric conduction experiment of solution in the current chemistry textbook for grade 9 published by People Education Press had some shortages, such as the potential safety hazard and clumsy instruments. This paper made an integrated experiment demonstration device for electric conduction of solution by using silver iodide battery, light-emitting diodes, etc, which made up for the lack of experiment in textbook. This device had the characteristics of artful, light and easy, and the effect was more obvious.
