Knowra Silver nitrate Silver nitrate Silver nitrate (AgNO₃) is a water-soluble inorganic salt composed of silver ions and nitrate ions. It is used in chemical analysis, synthesis, photography, and topical cautery.
Silver ion : The positively charged silver species, Ag⁺, formed when silver compounds dissolve or ionize. Dissolved silver nitrate releases Ag⁺, the reactive species behind precipitation, antimicrobial action, and staining.
Gravimetric analysis : A quantitative analytical method that determines an analyte's amount from the mass of a separated solid. Silver nitrate can precipitate halides for measurement by weighing the resulting silver halide.
Ionic compound : A substance composed of positively and negatively charged ions held together by electrostatic attraction. Silver nitrate is an ionic solid built from Ag⁺ and NO₃⁻.
Silver nitrate burn : A chemical injury caused by contact with silver nitrate, often leaving dark staining and tissue damage. The compound's caustic action can injure skin and eyes during handling or treatment.
Nitrate ion : The polyatomic anion NO₃⁻, the conjugate base of nitric acid. NO₃⁻ balances the charge of Ag⁺ in the salt and usually remains a spectator ion in its reactions.
Mohr method : A titration method that measures chloride or bromide using silver nitrate and chromate indicator. This classical assay uses silver nitrate to precipitate halide until excess silver forms a colored endpoint.
Nitric acid : A strong mineral acid with formula HNO₃ that is also an oxidizing agent. It supplies the nitrate component in silver nitrate preparation and related reactions.
Argyria : A usually permanent blue-gray discoloration of skin or tissues caused by accumulated silver. Repeated or excessive silver exposure, including from silver compounds, can cause this condition.
Silver halide : A compound of silver and a halogen, often sparingly soluble and sensitive to light. Silver nitrate supplies Ag⁺ that precipitates halide ions as photographic silver halides.
Photographic fixer : A chemical bath that removes undeveloped silver halides from photographic film or paper. Silver nitrate is a source material for silver halides used in conventional photographic emulsions.
