What is silver nitrate?
Chemical Properties of AgNO₃
Silver nitrate (AgNO₃) is an inorganic salt formed by the reaction of metallic silver with nitric acid. It is an ionic compound in which the silver ion Ag⁺ occurs in the crystal structure alongside the nitrate ion NO₃⁻. Due to the presence of silver in the +1 oxidation state, silver nitrate exhibits oxidizing properties and is a strong bactericide. This compound is highly soluble in water, making it useful in many chemical and analytical applications.
Structure and Basic Properties of the Compound
Silver nitrate forms an ionic structure composed of Ag⁺ cations and NO₃⁻ anions. The nitrate ion has a planar structure with a central nitrogen atom surrounded by three oxygen atoms. AgNO₃ is a crystalline, anhydrous, light-sensitive substance—when exposed to light, it decomposes with the release of metallic silver, leading to the substance’s characteristic darkening. The molar mass of silver nitrate is 169.87 g/mol.

Applications of silver nitrate
Industrial and laboratory applications
Silver nitrate is widely used in the chemical industry as a substrate in the synthesis of other silver compounds, including colloidal silver and silver nanoparticles. In the electronics industry, it is used to produce conductive pastes and conductive coatings on ceramic and glass surfaces. In analog photography, AgNO₃ was a key component of photosensitive emulsions, although its importance in this industry has now declined significantly. In chemical laboratories, it serves as a reagent for titration, synthesis, and the detection of chloride, bromide, and iodide ions.
Applications in Analytical Chemistry
In analytical chemistry, silver nitrate is used as a reagent for the determination of halide ions by argentometric titration (the Mohr and Volhard methods). It is also used in qualitative analysis to identify the presence of chlorides, bromides, and iodides in solutions. AgNO₃ is used in chromatography and in the preparation of samples for spectroscopic analysis. In microbiology and molecular biology, it is used to stain specimens and to detect proteins and DNA in gel electrophoresis.
Historical Applications in Medicine and Technology
Silver nitrate played a significant role in medicine, particularly in the 19th and early 20th centuries. In the form of solid sticks, known as “hellstone” (lapis infernalis), it was used as a bactericide and cauterizing agent in the treatment of wounds, ulcers, and inflammation of the mucous membranes. In ophthalmology, AgNO₃ solutions were used prophylactically in newborns to prevent infections (the Credé procedure), although this practice has now been replaced by antibiotics in most countries. In photography, it was an essential component of photosensitive emulsions and in the processes of developing and fixing photographs. Today, most of these applications have been replaced by modern technologies, although AgNO₃ is still used in certain niche medical and industrial applications.

Physicochemical Properties of Silver Nitrate
Physical Properties (Appearance, Solubility)
Silver nitrate is a colorless, crystalline solid that darkens when exposed to light, taking on a gray or black color due to the release of metallic silver. It is highly soluble in water—its solubility at 20°C is approximately 222 g/100 mL of water. AgNO₃ is also soluble in ethanol, though to a lesser extent. The compound’s melting point is 212°C, while thermal decomposition begins at approximately 440°C and proceeds fully above 600°C. The density of silver nitrate is approximately 4.35 g/cm³.
Chemical Properties (Reactivity, Oxidation)
Silver nitrate is a strong oxidizing agent, which is due to the presence of silver in the +1 oxidation state. In reactions with reducing agents, such as aldehydes, alcohols, or organic compounds containing functional groups, AgNO₃ is reduced to metallic silver. With chloride, bromide, and iodide ions, it forms sparingly soluble silver salts (AgCl, AgBr, AgI), which precipitate from solution. In the presence of bases, AgNO₃ reacts to form silver oxide (Ag₂O), which is a dark brown precipitate. The compound is also photosensitive—it decomposes under the influence of UV light, releasing metallic silver.

Silver nitrate has a wide range of applications in the chemical and electronics industries, as well as in analytical laboratories.
It is used for the synthesis of other silver compounds, the production of conductive pastes, and in analytical chemistry
as a titration reagent and for the detection of halide ions. Historically, it was used in medicine
as a bactericide and cauterizing agent in the treatment of wounds and inflammation. In analog photography, it served
as a component of photosensitive emulsions.What is another name for silver nitrate?
Silver nitrate in the form of cautery sticks is known as “hellstone” (lapis infernalis).
In chemical nomenclature, it is listed as silver(I) nitrate(V), argenti nitras in Latin, and
silver nitrate in English. It should not be confused with lapis lazuli—a blue gemstone.Is silver nitrate safe?
Silver nitrate is a hazardous substance—it is corrosive, has oxidizing properties, and is toxic
to the aquatic environment. It can cause skin burns, eye damage, and permanent black discoloration.
When used in accordance with health and safety regulations and with personal protective equipment (goggles, gloves), it is safe
for professional use. Avoid contact with skin, eyes, and clothing.Does silver nitrate stain?
Yes, silver nitrate leaves black stains that are difficult to remove. When exposed to light, it decomposes,
producing metallic silver, which causes dark discoloration of the skin and fabrics. While working, protect
your clothing and avoid letting the substance come into contact with surfaces. If the substance comes into contact with your skin, wash it off immediately
with soap and water.How should silver nitrate be stored?
Silver nitrate should be stored in its original, tightly sealed container, protected from light.
The optimal storage temperature is 15–25°C. Keep the product away from organic materials,
flammable substances, and reducing agents. The container should be tightly closed after each use.Does the sale of silver nitrate require a license?

The product is neither a drug precursor nor an explosive. However, regulations
governing the handling of hazardous substances must be followed, including the provision of an SDS and appropriate labeling.What is the shelf life and what are the shipping conditions?
When stored properly, silver nitrate has a shelf life of at least 3 years. The product is stable,
but exposure to light causes gradual decomposition with the release of metallic silver. Transportation is carried out in accordance
with ADR as a Class 5.1 hazardous material, in leak-proof and secure packaging.How much does silver nitrate cost?
The price depends on the chemical purity, product form, order size, and the current price of silver.
For retail packages (25–500 g), prices range from several dozen to several hundred zlotys, while for
wholesale orders of 50+ kg, we provide customized quotes with discounts. Contact us for a quote.What are the alternatives and substitutes for silver nitrate?
Depending on the application, alternatives may include other silver salts, such as silver acetate, silver chloride,
or silver sulfate. In bactericidal applications, colloidal silver or silver nanoparticles can be used.
In analytical chemistry, mercury(I) nitrate can be used as a substitute in the Volhard method. The choice depends on the process requirements.
