前文曾述及在70°时,与自由草酸浓度较低之溶液成平衡的固相,似非具固定组成的化合物,而是组成随浓度变化的混晶.为确证这一点,故用前两篇中所用的方法先后进行了下述二系列的实验.其一仍从[Co(NH3)5H2O]2(C2O4)3·4H2O出发,在70°及自由草酸浓度为1.9-2.3M范围内研究本体系.另一系列则从[Co(NH3)5C2O4]2C2O4·4H2C2O4出发,在70°及自由草酸浓度为1.9-4.0M范围内研究同一体系.

In a preceding report[1],we have pointed out that at 700 and when the concentration of the free oxalic acid was less than 2 M,instead of a compound with definite composition,the existence of a mixed crystal phase in equilibrium with the liquid seems to have been observed.
