Silver Molybdate
Silver molybdate is a chemical compound that consists of silver (Ag), molybdenum (Mo), and oxygen (O). Its chemical formula is Ag2MoO4.
Silver molybdate can be prepared by reacting silver nitrate (AgNO3) with ammonium molybdate ((NH4)6Mo7O24) in aqueous solution. The resulting precipitate is then washed, dried, and heated to form the silver molybdate powder.
Silver molybdate is a yellow-orange colored powder that is insoluble in water but soluble in acids. It has a crystalline structure and belongs to the monoclinic crystal system.
One of the main applications of silver molybdate is as a catalyst for organic reactions such as olefin oxidation and selective hydrogenation. It is also used as a component in photochromic materials, which change color when exposed to light.
In terms of safety, silver molybdate should be handled with care as it can irritate the skin, eyes, and respiratory system if inhaled. It is also classified as harmful if swallowed and may cause damage to organs if ingested. Proper protective equipment and handling procedures should be followed when working with this material.
