溶液的pH计算方法就是从定义出发,根据表达式来求pH.计算pH的难点在于找出溶液的氢离子浓度c(H+).下面归类溶液pH的计算类型及方法.一、单一溶液pH值的计算1.强酸溶液例110mL,0.05mol·L-1的H2SO4溶液,pH值为.解析:c(H+)=0.05mol·L-1×2=0.1mol·L-1pH=-lgc(H+)=-lg0.1=1方法: The solution pH calculation method is based on the definition, according to the expression to find the pH. The difficulty in calculating the pH is to find out the hydrogen ion concentration of the solution c (H +). Below is the classification of the solution type and method of calculation of the pH. A single solution pH The calculation of the value 1. Strong acid solution example 110mL, 0.05mol · L-1 H2SO4 solution, pH value. Analysis: c (H +) = 0.05mol · L-1 × 2 = 0.1mol · L-1pH = -lgc ( H+)=-lg0.1=1 method:
