摘要
用pH玻璃电极和甘汞电极组成的电池,测试了25℃时丙酸在含有10％、20％、30％、40％、50％和60％(质量百分比)正丙醇的正丙醇—水介质中的离解常数,看出丙酸的pKa随正丙醇成份的增多而减小。
Dissociation constants of Propionic acid in n-propanol-water media containing 10.20. 30, 40, 50 and 60 mass% of n-propanol at 25 ℃ have been determined by potentiometric method. The pKa of Propionic acid was diminished as the proportion of n-propanol component in the medium increased.
