Abstract The “nail corrosion experiment” in the ninth grade chemistry textbook of Shanghai Education edition has some problems such as long reaction time, difficult classroom operation, low visibility, difficult control variables.Combined with digital sensing technology, a series of explorations and improvements were carried out on the experiment, and two groups of comparative experiments were designed to quantitatively determine the oxygen consumption of reduced iron powder in the process of rust, to explore the conditions of iron and steel corrosion and the factors that affect the corrosion rate of iron and steel.
