为1.15×10-3字面112摩尔-112分-1。这比相同pH范围内硫化镉沉淀的常量高出42%。在给定硫化物浓度下，饱和溶液中镉(II)的浓度应比类似溶液中铅(II)的浓度高52%(3)。在这种溶解度的增加和速度常数的减小之间可能有某种联系。在确定其他碱性阳离子的沉淀速率的速度常数之前，不能假定这样的关系。
was 1.15 X 10-3 liter112 mole-112 minute-1. This is 42% higher than the constant for the precipitation of cad-mium sulfide in the same pH range. The concentration of cadmium (II) in a saturated solution at a given sulfide concentration should be 52% greater than that of lead (II) in a similar solution (3). There may be some correlation between this increase in solubility and the decrease in the velocity constant. Such a relationship cannot be postulated until the velocity constants for the rate of precipitation of other basic cations are determined.
