通过滴定结果,论证了分别用中性红和酚酞作指示剂检测硫酸和硫酸铵,能准确测定电解液中硫酸和硫酸铵的含量。同时介绍了实际操作时的注意事项.
Through the titration results, it is demonstrated that sulfuric acid and ammonium sulfate are respectively detected by using neutral red and phenolphthalein as indicators, and the content of sulfuric acid and ammonium sulfate in the electrolyte can be accurately determined. At the same time introduced the actual operation of the precautions.
