Abstract This paper explored change of pH in the reaction of aluminum sulfate solution and sodium hydroxide through digital experimental method, the change curve between pH and the volume of sodium hydroxide solution was obtained, so the relationship between the amount of sodium hydroxide and formation and dissolution of aluminum hydroxide precipitation was got. This research could change people's misunderstanding on amphoteric aluminum hydroxide, played an active role in the high school chemistry teaching.
