摘要
通过使用品红溶液、硫酸铜溶液及泡泡水等,可以验证浓硫酸与锌粒在加热条件下有氢气生成.提出产生氢气的原因与浓硫酸的自偶电离有关,并用多种金属进行验证.
Used magenta solution, cupric sulfate solution and bubble water, this paper verified that hydrogen was generated when concentrated sulfuric acid and zinc particles were heated together. It was suggested that hydrogen generation was related to the self-ionization of concentrated sulfuric acid, which was confirmed by several metals.
