硫酸在水溶液中按以下两步解离:H_2SO_4=H~+十HSO_4~-HSO_4-=H~+十SO_4~(2-) 一次解离是完全的,但在二次解离时它是一中等程度的弱酸,这一事实使涉及到硫酸溶液的湿法冶金反应的解释复杂化了。在讨论含硫酸的电解液的电导率时,以及在讨论185和200℃温度下共存的金属硫酸盐对硫酸铁溶蔽水解的影响时,均通过估算氢离子浓度的方法讨论了硫酸的二次解离在其中的作用。结果可以看到,硫酸氢根离子的缓冲作用对湿法冶金反应是十分重要的。
Sulfuric acid is dissociated in aqueous solution in the following two steps: H 2 SO 4 = H ~ + + HSO 4 ~ -HSO 4 - = H ~ + SO 4 ~ (2-) The primary dissociation is complete but at the time of secondary dissociation it is one The fact that there is a moderate degree of weak acid complicates the interpretation of the hydrometallurgical reaction involving the sulfuric acid solution. In discussing the conductivity of sulfuric acid-containing electrolytes and the effects of metal sulfates coexisting at temperatures of 185 and 200 ° C on the water-soluble hydrolysis of ferric sulphate, the secondary The role of dissociation in it. As a result, it can be seen that the buffering effect of hydrogen sulfate ions is very important for the hydrometallurgical reaction.
