电位滴定回归分析法测定NH4+及其离解常数
Determination of weak Acid,Dissociation Constant of Weak Acid by Potential Titration and Regression Analysis
【摘要】 铵离子(NH4+)是一种极弱酸,测定其含量通常手续比较繁琐.本研究采用电位滴定回归分析法滴定极弱酸,直接计算含量及其离解常数,结果比作图法准确.测定 NH4+的离解常数与文献值甚为接近.
【Abstract】 This paper describes the method for determination of weak acid and dissociation constant of weak acid.The method is based on potential titration and regression analysis.The NH4+ is determinated in this way and the results are very good.
