Key Properties
Silver thiocyanate is an insoluble silver(I) salt with the molecular formula AgSCN and a molecular weight of 165.95 g/mol. It is primarily recognized for its role as a titrant in Volhard's method, a classical analytical technique used for the determination of halides in solution. This compound is notable for its light sensitivity, which necessitates careful handling and storage to maintain its integrity. With a purity of 98%, it is suitable for high-precision analytical applications in laboratories.
Also known as Silver(I) thiocyanate, Thiocyanic acid silver salt.
