摘要
依据文献理论和紫外-可见光谱法证明了Fe^(2+)与SCN^(-)能够形成化学键。又通过传统对比实验,利用化学平衡移动原理和沉淀溶解平衡原理,进一步验证了Fe^(2+)与SCN^(-)能发生络合反应。
According to the theories reported in literature and UV-visible absorption spectroscopy, it is proved that Fe^(2+) can form chemical bond with SCN^(-). Based on the principle of chemical equilibrium movement and the principle of precipitation and dissolution equilibrium, a controlled experiment further verifies that complexation reaction can occur between Fe^(2+) and SCN^(-).
