本文介绍了一种确定和获得柠檬酸铜配合物在酸性溶液中不稳定常数的方法。所形成的化合物的性质主要由柠檬酸盐-铜比率决定，其次由溶液的年龄决定。形成的初始化合物为[Cu（HCit）（H2 Cit）~]。如果柠檬酸盐浓度至少是铜的30倍！）当柠檬酸-铜比小于30时，上述络合物加入铜离子并释放出氢离子。在总铜浓度低的溶液中，加入二价铜离子是一个相对缓慢的过程。在柠檬酸盐-铜比率非常低[1比2]的溶液中出现的最终产物是不溶性固体Cu 2 [CeH< 07]。
A method for identifying and obtaining instability constants of copper citrate coordination compounds in acid solution is described. The nature of the compound formed is determined primarily by the citrate-copper ratio and in a secondary manner by the age of the solution. The initial compound formed is [Cu (HCit)(H2Cit)~]. If the citrate concentration is at least 30 timesthe copper!) concentration, this compound is stable, but if the citrate-copper ratio is less than 30 the above com-plex adds copper (II) ion and liberates hydrogen ion. The addition of the cupric ion is a relatively slow process in solutions of low total copper concentration. The ultimate product appearing in solutions of very low citrate-copper ratio [1 to 2] is the insoluble solid Cu2 [CeH< 07.]
