摘要
本文采用分光光度等吸收点法测定了溴邻笨三酚红的全部五个解离常数。其结果如下: k_(α_1)=0.99(pk_(α_1)=0.01);k_(α_2)=8.13×10^(-5)(pk_(α_2)=4.09);k_(α_3)=1.40×10^(-6)(pk_(α_3)=5.58);k_(α_4)=3.44×1o^(-9)(pk_(α_4)=8.46)及k_(α_5)=2.75×10^(-12)(pk_(α_5)=11.53)。
In this paper the all of of five acid dissociation constants for Bromopyrogallol Red has been determined by spectrophotometric isobestic point method, The obtained results are as follows:
k_(α_1)=0.99(pk_(α_1) =0.01)
k_(α_2)=8.13×10^(-5)(pk_(α_2)=4.09)
k_(α_3)=1.40×10^(-6)(pk_(α_3)=5.85)
k_(α_4)=3.44×10^(-9)(pk_(α_4)= 8.46)
k_(α_5)=2.75×10^(-12)(pk_(α_5)=11.56)
