Application
Indium(III) sulfate serves a specific purpose in various chemical applications due to its unique properties as a grayish-white, deliquescent powder. It is primarily used in chemical synthesis and acts as a hardening agent in gold electroplating baths. Additionally, it plays a crucial role in the preparation of other indium-containing compounds, such as copper indium selenide. This compound, with its hydroscopic nature and monoclinic crystal structure, is available in different forms, including anhydrous powder, a hydrated salt with nine moles of associated water, and as a solution with varying water concentrations, up to its solubility limit. Despite its limited use, these characteristics make Indium(III) sulfate valuable in specialized applications.
