To solve the question regarding which compound gives a purple color with neutral FeCl₃, we can follow these steps:1. Understanding FeCl₃: - FeCl₃ (iron(III) chloride) dissociates in solution to form Fe³⁺ ions
copper reacts with moisture and.CO2in air to form a green coloured coating of basic copper carbonate on its surface. Silver acquires a black colour when exposed to air containingH2Sdue to the formation of silver sulphide on its surface. Based on the above paragraph, answer the following questi...
sulphides, carbides, and nitrides. Compared with physicochemical methods, biogenic nanoparticle synthesis is more economical and environmentally friendly84. To enhance organic synthesis, efforts should be focused on developing eco-friendly nanosynthesis techniques and scaling up laboratory research to industria...
