SILVER ARSENATE Chemical Properties,Usage,Production

Description

Silver arsenate is the silver salt of arsenate, being highly toxic. It has been used in qualitative analysis to distinguish between phosphate (Ag3PO4 is yellow) and arsenate (V) solutions. A qualitative test for arsenate ion provides the basis for a colorful demonstration of the principles of relative acid strength, solubility product, and effects of pH on solubility. Arsenates are used in some wood preservatives, finishing agents, and as reagents in various chemical reactions. It can be used as a component of high-conductivity material, and can be as a standard component of electrodes.
