Abstract The composition of solute and filter residue in “one metal reacts with a variety of salts in solution” and “one salt reacts with a variety of metals in solution” were dialyzed by the aid of number axis. It intuitively showed the reaction process and results, established a thinking model, and made it easy. It was good for students to master and apply.
