Abstract In order to facilitate students to understand the chemical equilibrium in depth. On the basis of the teaching materials,this paper used hand-held technology to quantitatively inquire the effect of multiple concentrations on the chemical equilibrium; the effect of the addition of crystals on the chemical equilibrium was also explored. By analyzing the experimental phenomena and graphs,it was concluded that the degree of chemical equilibrium was increasing in the direction of positive reaction with the increase of the concentration and mass of KSCN.
