| 摘 要： | 本文讨论了离子强度对盐类水解浓度平衡常数影响 ,指出在一定温度下 ,离子强度的增大 ,对一元弱酸强碱盐和强酸弱碱盐的水解浓度平衡常数趋向无影响 ;使一元弱酸弱碱盐的水解浓度平衡常数Kch 减小 ;对多元弱酸强碱盐的最后一级水解浓度平衡常数趋向无影响 ,其余各级水解浓平衡浓度平衡常数减小 ,以及相邻两级水解浓度平衡常数Kchi与Kch(i 1 ) 的比值减小

| Abstract: | This paper discusses the effect of ionic strength on saline hydrolysis concentration eguilibrium constant, on a certain temperature conditions, a rise in ionic strength has no effect on weakly alkaline salt and weakly acidic salt hydrolysis concentration equilibrium constant; decreases the salt made from weak acid and weak baes hydrolysis concentration equlibrium constant; has no effect on the last step of multivariant weakly acidic salt hydrolysis concentration equilibrium constant, decreases the other steps, and decreases the proportionality of contiguous two steps. |
