Ferric chloride, a chemical compound with the formula FeCl₃, is a crucial substance with diverse applications across various industries. Ferric chloride exists in two main forms: anhydrous and hydrated. The anhydrous form is a dark brown, crystalline solid, while the hydrated form is commonly found as a hexahydrate. It has a distinctive odor and is highly soluble in water, forming a yellow-brown solution. One notable property of ferric chloride is its ability to act as a Lewis acid, forming complexes with other substances. This characteristic makes it a valuable tool in various chemical processes.

While ferric chloride offers various benefits, its use raises environmental concerns. The disposal of spent ferric chloride solutions, especially from etching processes, requires careful handling due to the potential for heavy metal contamination. Efforts to minimize environmental impact include proper waste management and recycling processes. Moreover, the production of ferric chloride involves energy-intensive processes, contributing to its overall carbon footprint. Sustainable practices and technological advancements are being explored to mitigate these environmental effects.
