Abstract This paper used super absorbent resin to improve the design of three experiments “an acid-base reaction, sodium carbonate and sodium bicarbonate reacting with dilute hydrochloric acid respectively, exploring molecular motion phenomena”. The super absorbent resin, with a special structure, made experimental phenomena more obvious. The improved experiment was easy to operate and with high efficiency, and was worth extending to the demonstration experiment and the group experiment.
