Chromium sulfate, also known as chromic sulfate, is a chemical compound with the formula Cr2(SO4)3. It is commonly used in the tanning industry as a key component in the process of converting animal hides into leather. Chromium sulfate plays a critical role in fixing the tanning agents to the collagen fibers in the hide, resulting in durable and long-lasting leather products. Additionally, it has applications in the production of certain pigments, catalysts, and in wastewater treatment for the removal of heavy metals. Its ability to enhance leather quality and its utility in other industrial processes make chromium sulfate a valuable chemical compound in various applications.
