研究目的:一谈到制取氢气的原料,我们就会习惯地想到用金属和非氧化性强酸的稀溶液来反应。这种用来还原溶液中氢离子的金属必须满足以下要求:该金属的标准电极电势要比氢低,即比氢活泼;该金属与非氧化性稀强酸反应产生的盐在水中的溶解度要大;该金属与非氧化性稀强酸反应的速率适中,产生的氢气流平稳;
The purpose of the study: When it comes to the raw materials for the production of hydrogen, we will conventionally think of using dilute solutions of metal and non-oxidizing strong acids. The metal used to reduce the hydrogen ions in the solution must meet the following requirements: the standard electrode potential of the metal is lower than that of hydrogen, that is to say it is more active than hydrogen; the salt produced by the reaction of the metal with a non-oxidizing dilute strong acid has a large solubility in water ; The rate of reaction of the metal with the non-oxidizing dilute strong acid is moderate and the hydrogen flow produced is stable;
