The dissociation constants for oxalic acid in 3.0M sodium perchlorate medium at 25.0 degrees have been determined by potentiometric and spectrophotometric titrations. The values for the concentration constants are K(a1) = (5.32 +/- 0.15) x 10(-2) and K(a2) = (1.53 +/- 0.02) x 10(-4). The absorption spectra for the individual oxalate species are reported.
通过电位滴定法和分光光度滴定法测定了草酸在25.0摄氏度、3.0M高氯酸钠介质中的解离常数。浓度常数的值为K(a1) = (5.32 +/- 0.15) x 10(-2)和K(a2) = (1.53 +/- 0.02) x 10(-4)。报告了各个草酸盐物种的吸收光谱。
