摘要
用玻璃电极和甘汞电极组成的电池,测定25℃时丙酸在含有10%、20%、30%、45%和60%(质量百分比)乙醇的乙醇-水介质中的离解常数,看出丙酸的pKa值随介质中有机成分的增多而增大.
In this paper dissociation constants of proplonic acid in ethanol-water media containing 10, 20, 30, 45 and 60 mass% of ethanol at 25℃ have been determined using glass and mercuric-mercurous chloride electrodes. The pK_α Values of propionic acid at the temprature increase as the proportion of organic component in the medium increases.
