Silver Products
Silver salts are used in many fields and Industries all over the world. Lab Chemicals Trading Company has its own factory for manufacturing the following Silver salts:
A- Silver Nitrate 99.98%
Silver nitrate is an inorganic compound with chemical formula AgNO3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called lunar caustic because silver was called luna by the ancient alchemists, who believed that silver was associated with the moon.
In solid silver nitrate, the silver ions are three-coordinated in a trigonal planar arrangement.
Silver nitrate can be prepared by reacting silver, such as a silver bullion or silver foil, with nitric acid, resulting in silver nitrate, water, and oxides of nitrogen.
3 Ag + 4 HNO3 → 3 AgNO3 + 2 H2O + NO
3 Ag + 6 HNO3 → 3 AgNO3 + 3 H2O + 3 NO2
This is performed under a fume hood because of toxic nitrogen oxide(s) evolved during the reaction.

B- Silver Chloride 99.9%
Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl+ and Pb2+). Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grayish or purplish coloration to some samples. AgCl occurs naturally as a mineral chlorargyrite.
Silver chloride is easily synthesized by combining aqueous solutions of silver nitrate and sodium chloride.
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

C- Silver Oxide [Silver (I) Oxide] 99.99%
Silver oxide (Ag2O) cas no: 20667-12-3 , produced when silver nitrate solutions are treated with a base, is used as a positive electrode (anode) in watch batteries. Silver carbonate (Ag2CO3) is precipitated when silver nitrate is treated with sodium carbonate (Na2CO3).
2 AgNO3 + 2 OH− → Ag2O + H2O + 2 NO3−
2 AgNO3 + Na2CO3 → Ag2CO3 + 2 NaNO3
2 AgNO3 + 2 OH− → Ag2O + H2O + 2 NO3−
2 AgNO3 + Na2CO3 → Ag2CO3 + 2 NaNO3
D- Silver Sulphate 99.8%
Silver sulfate (Ag2SO4) is an ionic compound of silver used in silver plating and as a non-staining substitute to silver nitrate. This sulfate is stable under ordinary conditions of use and storage, though it darkens upon exposure to air or light. It is minimally soluble in water.
Silver sulfate is prepared by adding sulfuric acid to a solution of silver nitrate:
2 Ag+(aq) + SO42-(aq) → Ag2SO4 (s)
The precipitate is then washed with hot water and preparation is under ruby red illumination.
