Wood Preservation: Basic chromium sulfate is used as a wood preservative to protect timber from decay, fungal growth, and insect attacks. It helps to fix dyes onto fabrics and improve colorfastness. In addition to its use in tanning, basic chromium sulfate is employed in other applications, including:ĭyestuff and Pigment Production: It serves as a mordant, a substance that enhances the affinity of dyes or pigments for textile fibers. It also enhances the leather's ability to resist water and impart a soft texture. The compound helps to cross-link collagen fibers, making the leather more stable, resistant to decomposition, and less susceptible to shrinkage. It plays a crucial role in the process of converting raw hides or skins into leather. It is derived from the reaction between chromium(III) oxide (Cr2O3) or chromium(III) hydroxide (Cr(OH)3) and sulfuric acid (H2SO4).īasic chromium sulfate is primarily used in the tanning industry as a tanning agent and a leather preservative. It is also used in dyeing of khaki cloth and in manufacture of chrome-based dyestuffs.īasic chromium sulfate, also known as chromium(III) sulfate or chromic sulfate, is a chemical compound with the formula Cr(OH)SO4. What is the Colour of chromium sulphate? Where is chromium sulfate found? What is the formula of chromium sulfate?
