Product Overview

Silver Nitrate 99% Extra Pure (CAS No. 7761-88-8) is the nitrate salt of silver(I) and provides a soluble source of Ag⁺ ions for inorganic, preparative and photochemical laboratory chemistry. Silver(I) displays strong affinity for halide and several other donor anions, leading to characteristic precipitation and complex-formation reactions. Silver nitrate is also photosensitive and can undergo reduction to elemental silver under suitable chemical or photochemical conditions.

The Extra Pure grade is intended for general preparation of silver salts, precipitation studies, inorganic synthesis and laboratory investigations requiring a soluble silver(I) reagent. Reaction behaviour remains dependent on light exposure, complexing species, reducing conditions and the chemistry of the counter-anion being introduced.

Typical Applications

• Preparation of silver halides and other sparingly soluble silver salts.
• Starting material for synthesis of silver(I) coordination compounds.
• Precipitation and solubility studies involving silver ions.
• Photochemical studies of silver compounds.
• Preparation of metallic silver or silver-containing materials by suitable reduction chemistry.
• General inorganic and materials research requiring a soluble silver source.

Common Synonyms

• Silver(I) nitrate
• Nitric acid silver(I) salt
• Lunar caustic

Storage Conditions

Store tightly closed and protect from light to limit photochemical darkening and reduction of silver species. Prevent contamination by halides, reducing substances and organic residues that can precipitate or consume silver ions and change reagent composition.
