| Abstract: | the electrolytic water experiment is one of the important experiments in high school chemistry lecture.Adding NaOH or H2SO4 into water improves the experiment effects.Moreover,the concentration of NaOH and H2SO4,the materials made of electrode,adscititious pressure and experimental temperature influence the experiment results in some extent.However,adding Na2SO4 could also improve the experiment effects. |
