Abstract

The investigation on calcium (II) oxalate is carried out in order to study its solubility in different ionic media. In the same conditions the protonation constants of oxalate and the stability of complex species have been determined. As the stoichiometric composition of the solid calcium (II) oxalate prepared for the investigation was accurately checked, the salt CaC2O4 · H2O is proposed as universal (chelometry, redox, acidimetry) standard. Results of titrations support this possibility.

草酸钙作为溶解度和通用标准的研究
对草酸钙(II)在不同离子介质中的溶解度进行了研究。在相同条件下测定了草酸的质子化常数和络合物的稳定性。对制备的固体草酸钙(II)的化学计量成分进行了准确的测定,提出以CaC2O4·H2O盐作为通用(螯合、氧化还原、酸化)标准盐。滴定结果支持这种可能性。
