采用徐光宪等的极谱半波电势的方法和作图法,测定铅和醋酸根所成络合物的各级络合常数,在25℃,以高氯酸纳维持离子强度μ=2.5时,测得:K1=95.5±3.5;K2=1350±28;K3=912±18;K4=501±15。并计算不同浓度醋酸钠溶液中各种络离子的百分组成和热函数与自由能的改变。

The half wave potential of the lead ions was determined at 25℃ in sodium perchlorate-sodium acetate mixture, over a concentration range of 0.01-0.13 M acetate ions,and at an ionic strenth 2.5.The succestve stability constants were found to be:K1=95.5±3.5;K2=1350±28;K3=912±18;K4=501±15
