极弱酸恒pH法测定条件的研究
Studies on the Conditions for Determining Extra Weak Acids by the Constant pH Method
【摘要】 应用误差理论研究了恒pH法测定极弱酸时pH值对浓度和电离常数的误差产生的影响，给出了适宜的pH值范围：pKa-0．5＜pH＜pKa＋2．0：对NH4Cl和H3BO3进行了实验研究．
【Abstract】 the error theory, the influence of pH values on the errors of concentration and iozization constant were investigated when measuring extra weak acids with the contant pH method. The optimum determination range of pH values have been obtained as following : pKa-0．5＜pH＜pKa＋2．0 The experimental results were satisfactory as regards to the quantitative analysis of NH4Cl and H3BO3
