What is copper(II) nitrate trihydrate?
Copper(II) nitrate trihydrate is an inorganic chemical compound belonging to the group of nitric acid salts, in which the copper(II) ion Cu²⁺ is bound to two nitrate anions NO₃⁻. The most common and widely used commercial form is the trihydrate—that is, the form containing three molecules of water of crystallization, denoted by the formula Cu(NO₃)₂·3H₂O. Under normal conditions, this substance occurs as blue-green crystals that are highly soluble in water.
The compound belongs to the group of inorganic oxidizing agents, which means it can donate oxygen to other substances, accelerating their oxidation. For this reason, copper(II) nitrate is widely used both in chemistry laboratories and in many industrial sectors—ranging from ceramics and metallurgy, through photography, to pyrotechnics.
Chemical formula and properties of Cu(NO₃)₂·3H₂O
The molecular formula of copper(II) nitrate trihydrate is Cu(NO₃)₂·3H₂O, where Cu represents copper in the +2 oxidation state, NO₃ is the nitrate (V) anion, and 3H₂O indicates three molecules of water of crystallization that are part of the crystal structure. The molar mass of the trihydrate is 241.60 g/mol, while the anhydrous form of Cu(NO₃)₂ has a molar mass of 187.56 g/mol.
The compound is registered under CAS number 10031-43-3 (for the trihydrate) and EC number 221-838-5. In IUPAC nomenclature, the full name is bis(nitrato)copper(II) trihydrate. In commercial use and technical documentation, one may also encounter designations such as copper(II) nitrate trihydrate, cupric nitrate trihydrate, or the abbreviation Cu(NO₃)₂·3H₂O.
Structure and Basic Properties of the Compound
Copper(II) nitrate is an ionic salt—in its crystal structure, Cu²⁺ ions are surrounded by NO₃⁻ anions and water molecules, forming a characteristic crystal lattice responsible for the compound’s blue-green color. This color is typical of copper(II) compounds and results from the presence of Cu²⁺ ions that absorb visible light in the red-orange range.
The trihydrate is stable at room temperature (up to about 26°C). At higher temperatures, the trihydrate gradually loses its water of crystallization—heating leads to successive dehydration. The melting point of the trihydrate crystals is approximately 114°C and occurs with simultaneous loss of water. Further heating above approximately 170°C leads to thermal decomposition with the release of nitrogen oxides (NOₓ) and copper oxide (CuO). The compound is highly hygroscopic—it absorbs moisture from the environment, which must be taken into account during storage.

Copper(II) nitrate trihydrate is a commonly used chemical reagent in analytical, research, and educational laboratories. It is used as a substrate in the synthesis of copper compounds, a source of Cu²⁺ ions in precipitation reactions, and a reagent in qualitative and quantitative analysis. In high school and college chemistry, copper(II) nitrate is a classic reagent for demonstrating redox reactions, reactions with hydroxides (formation of Cu(OH)₂), carbonates, and ammonia (formation of a tetraamine copper complex with an intense blue color).
In research laboratories, the compound is used as a precursor in the synthesis of copper oxide (CuO), copper nanoparticles, and various copper coordination complexes. Copper nitrate solutions are also used as electrolytes in electrochemistry and as a component of electroplating baths.
Industrial applications – ceramics, metal patination
In the ceramics and glass industries, copper(II) nitrate is used as a colorant and refining agent. During high-temperature firing of ceramics, it decomposes into copper oxide (CuO), which imparts characteristic shades to glazes—ranging from green through turquoise to black—depending on the furnace atmosphere and the composition of the ceramic body.
In metallurgy and arts and crafts, copper nitrate is widely used for patination and chemical coloring of metal surfaces—primarily copper, bronze, brass, zinc, and tin. Solutions of copper nitrate, often combined with ammonium salt or acetic acid, produce durable, aesthetically pleasing patinas in shades of green, blue, and brown. Copper nitrate is also used to polish iron and steel in finishing processes.
Copper nitrate as an oxidizer in pyrotechnics and photosensitive paper
Due to its oxidizing properties, copper(II) nitrate is used in pyrotechnics as a component of oxidizing compositions. Its use in pyrotechnics is subject to national and EU regulations—the purchaser is required to independently verify the legal requirements applicable to their business.
Historically, copper nitrate was used in the production of photosensitive paper (the ozalid process). This method is no longer widely used industrially.

Copper(II) nitrate trihydrate in its solid form forms blue-green crystals with a characteristic metallic luster. The substance is odorless, hygroscopic, and highly soluble in water—its solubility at 20°C is approximately 145 g/100 mL. It is slightly soluble in ethanol; practically insoluble in acetone and diethyl ether.
The density of the trihydrate is 2.05 g/cm³. Aqueous solutions have a characteristic blue color. Thermal decomposition occurs above approximately 170°C with the release of nitrogen oxides and copper oxide.
Chemical Properties – Reactivity, pH, Oxidation
Copper(II) nitrate is a strong oxidizing agent—the nitrate anion NO₃⁻ can donate oxygen under appropriate conditions. This reaction is particularly significant when the substance comes into contact with organic compounds, carbon, sulfur, and metals—hence the health, safety, and ADR transportation requirements.
The aqueous solution is acidic (pH approx. 3.0–4.0 at 50 g/L) due to the hydrolysis of Cu²⁺ ions. In an alkaline environment, copper nitrate reacts with hydroxides to form a blue Cu(OH)₂ precipitate, which turns into black CuO when heated. With carbonates, it forms basic copper carbonate (patina on copper surfaces).
Anhydrous Form vs. Trihydrate – Practical Differences
Cu(NO₃)₂·3H₂O trihydrate and the anhydrous form Cu(NO₃)₂ are available on the market. The trihydrate is generally more stable in storage and easier to dose; the anhydrous form has a higher active ingredient content by weight, as well as higher reactivity and hygroscopicity. In most applications, the trihydrate is preferred due to its ease of handling, availability, and price.
