Transition metal compounds
Transition metal compounds. These have intense colours because of the electronic structure of transition metals, and the hydration of most of the compounds with water. The formulae for the bottom row are (left to right): nickel sulphate (NiSO4.6H2O), cobalt chloride (CoCl2.6H2O), copper (II) sulphate (CUSO4.5H2O), potassium iron (III) cyanide (also called potassium hexacyanoferrate (III), K3[Fe{CN}6]). At upper left is iron (II) sulphate (FeSO4.7H2O). At upper right is chromium (III) sulphate (Cr2[SO4]3)

EDITORS COMMENTS
This print showcases a collection of transition metal compounds, each displaying vibrant and intense colors due to the unique electronic structure of these elements. The compounds' striking hues are further enhanced by their hydration with water. Starting from the bottom row, we have nickel sulphate (NiSO4.6H2O), cobalt chloride (CoCl2.6H2O), copper (II) sulphate (CUSO4.5H2O), and potassium iron (III) cyanide, also known as potassium hexacyanoferrate (III) or K3[Fe{CN}6]. At the upper left corner, we find iron (II) sulphate (FeSO4.7H2O), while at the upper right corner rests chromium (III) sulphate (Cr2[SO4]3). This mesmerizing composition not only highlights the diverse range of colors exhibited by these inorganic compounds but also serves as a visual representation of their various oxidation states and contrasting properties. The solid forms and powdery textures add an element of depth to this laboratory scene, evoking curiosity about their chemical characteristics. Through this photograph captured by Science Photo Library, viewers are invited to explore the fascinating world of transition metals and delve into their intricate chemistry—where color becomes a powerful tool for comparison and understanding within scientific research contexts.
