无机化合物颜色是一个重要而复杂的问题,现就三个方面的问题作一些深入的探讨。 1 颜色与混合氧化态 物质中的某一种元素如果存在两种不同的氧化态时,则该物质往往显示深而浓重的颜色,这一类深颜色的物质在无机化合物中为数不少,许多变价金属元素,尤其是d区过渡元素更易形成混合氧化态化合物。最常见具有混合氧化态化合物的元素有Cu、Au、Mo、Fe、Ni,Pt、Pd、Sb等,现简单介绍其中的Au、Pt、Pd。 The color of inorganic compounds is an important and complex issue. Now we will make some in-depth discussions on the three aspects of the problems. 1 color and mixed oxide state of a certain element If there are two different oxidation states, the material often shows deep and thick colors, this type of dark-colored material in inorganic compounds, many Varying metal elements, especially the transition elements in the d region, are more likely to form mixed oxide compounds. The most common elements with mixed oxidation state compounds are Cu, Au, Mo, Fe, Ni, Pt, Pd, Sb and so on.
