根据中学化学教学大纲的要求,对溶液pH值的计算只要求掌握强酸、强碱溶液的pH值计算。为此,有关溶液pH值的计算主要应掌握以下几种类型。一、求强酸、强碱溶液的pH值 1.已知强酸或强碱溶液的浓度,求溶液的pH值。例1.计算0.1mol/L HCl、H_2SO_4、NaOH溶液的pH值。解:HCl:0.1mol/L HCl溶液中 According to the requirements of the chemistry syllabus for middle schools, the calculation of the pH of the solution requires only the calculation of the pH value of the strong acid and alkali solution. To this end, the calculation of the pH of the solution should mainly be of the following types. First, the strong acid, strong alkali solution pH 1. Known strong acid or strong alkali solution concentration, seeking solution pH. Example 1. Calculate the pH of 0.1 mol/L HCl, H_2SO_4, and NaOH solutions. Solution: HCl: 0.1mol/L in HCl Solution
