It is commonly employed in the tanning industry for the production of leather goods, where it assists in the tanning process by cross-linking the proteins within the animal hide. This results in a durable and long-lasting material.
It is also utilized in the field of photography, particularly in the preparation of photographic materials. Chrome alum acts as a mordant, helping to fix and stabilize photographic dyes or pigments on the paper and improve their color rendition and longevity.
Furthermore, chrome alum finds applications as a catalyst in the synthesis of certain organic compounds and as an ingredient in the manufacturing of various types of catalysts. In the field of analytical chemistry, it is commonly used as a reagent for the determination of ammonia and phosphate ions.
