The acid dissociation constants of PAPAQ and PACPAQ were determined by spectrophotometric method. 用光度法测定TPAPAQ和PACPAQ的酸离解常数。
The negative value of logarithm of the acid dissociation constant pKa of the new agent p-MBPMP were determined in ethanol-water by pH-potentiometric titration. 测定了新试剂p-MBPMP在醇-水溶剂中的酸离解常数pK_a值.
For the some o hydroxylbenzenesulfonanilides,by using CNDO/2 and MMP2 method and connecting the pKa values of weak acid dissociation and the data of fasciolicidal activity; the relation between structure and activity has been studied preliminarily. 使用 CNDO/2和 MMP2方法
Acid dissociation and recombination of 15 pairs of haemoglobin mixtures matched from 6 mammalian haemoglobin (human, sheep, pig, rabbit, canine and camel haemoglobin) was investigated. 由6种哺乳动物(人、羊、猪、鬼、狗及骆驼)Hb粗合成15对Hb混合物,研究了它们的解离-再结合情现。
Effect of Solvent on Acid Dissociation of BDA 溶剂对联吡啶二酸酸解离常数的影响
Acids dissociate to give hydrogen ions. 酸分解时会释放出氢离子。
