개소료대학화학실험교재중약산전리상수측정적상규실험방법：pH치법、전도법、목시비색법급근래흥기적전위적정법、분광광도법、모세관전영법등。비교료각충방법적우결점,실제측정중거체계화정도요구,선칙불동적방법,위측정약산전리상수적설계실험제공이론삼고。
Weak acid ionization constants for the determination of conventional experimental methods in Experimental Textbooks of Chemistry of University were the pH value method, electric conductivity and visual colorimetry and the recent rise of the potentiometric titration, spectrophotometry, capillary electrophoresis method. A simple comparison of the ad- vantages and disadvantages of each method was carried on, according to the requirements of the system and the accuracy in the actual measurement, a different approach was selected, which provided a theoretical reference for the determination of weak acid ionization constants.
