From the precipitation borderline in the pM'-pC(H) diagram, determined experimentally under CO(2)-free conditions, the stability constants of the mononuclear species of ytterbium hydroxide have been established. The values found are log *beta(1) = -7.7, log *beta(2) = -15.5, log *beta(3) = -23.2, log *beta(4) = -37.5, log *beta(5) = -51.9, log *beta(6) = -66.2 and log *K(S0) = 18.0. The data refer to fresh precipitates, prepared at room temperature (21.5 +/- 0.2 degrees ) in sodium perchlorate medium with an ionic strength of 1. The formation of polynuclear hydroxide complexes has been considered and rejected as unlikely to occur.
在无二氧化碳条件下通过实验测定的pM'-pC(H)图中的沉淀边界,确定了氢氧化镱单核物种的稳定常数。得到的值为logβ(1)= -7.7,logβ(2)= -15.5,logβ(3)= -23.2,logβ(4)= -37.5,logβ(5)= -51.9,logβ(6)= -66.2和log*K(S0)= 18.0。这些数据指的是在室温(21.5±0.2摄氏度)下于离子强度为1的高氯酸钠介质中制备的新鲜沉淀物。多核氢氧化物络合物的形成已被考虑并被认为不太可能发生而被排除。
