摘要
研究了难溶复盐钼酸铵氧化钼的标准溶度积常数和不同温度下的溶解度,测定了同离子效应对溶解度的影响,并用红外光谱分析了其解离形式。实验结果表明:25℃的Ksp=c4(NH4+).c2(M oO42-).c3(M oO3)=2.13×10-13,溶解度随温度的升高显著增加,在有氯化铵存在下溶解度明显减小。所得结果对生产具有指导作用。
The standard solubility product and solubility of compound salt ammonium molybdate · molybdenum trioxide at 0 - 100 ℃ condition are studied. The same ion effect on its solubility is determined. Its dissociation mode is determined by infrared spectroscopy. The experiment results show that Ksp = c^4 （ NH4 ^＋ ） · c^2 （ MoO4^2- ） · c^3 （ MoO3 ） = 2. 13 × 10^-13 at 25 ℃. The solubility and solubility product of the compound salt increase with the temperature rising, and the solubility decreases in the presence of NH4Cl solution.
