He Aluminum nitrate Is the aluminum salt of nitric acid. Aluminum nitrate nonahydrate, at room temperature, is presented as a colorless solid with the odor of nitric acid.
They are not combustible, but can accelerate the combustion of combustible materials. If large amounts of aluminum nitrate are involved, or if combustible material is finely divided, an explosion may occur.
Prolonged exposure to fire or heat may result in an explosion. When they come into contact with the fire, they produce nitrogen oxides. Its uses include, oil refining, and leather dyeing and tanning.
It is a white salt, soluble in water, which is most commonly presented in its crystalline form nonahydrate (aluminum nitrate nonahydrate).

Characteristics of aluminum nitrate
Physical and chemical properties
- Aluminum nitrate belongs to the reactive group of inorganic nitrate and nitrite compounds.
- The nitrate ion is a polyatomic ion with the molecular formula NO3 - and is the conjugate base of nitric acid.
- Almost all inorganic salts of nitrate are soluble in water at standard temperature and pressure.
- Nitrate compounds have a wide range of uses that rely on their activity as oxidizing agents, the presence of freely available nitrogen or their high solubility.
Reactivity Alerts
Aluminum nitrate is a strong oxidizing agent.
Reactions with air and water
Aluminum nitrate is deliquescent (it has the property of absorbing moisture from the air to form an aqueous solution). It is soluble in water. Its aqueous solutions are acidic.
Inflammability
Nitrates and nitrites are compounds that are explosive. Some of these substances may decompose explosively when they are heated or are encased in a fire. They may explode by heat or contamination. Containers may explode when heated.
Special Hazards from Combustion Products: Toxic oxides of nitrogen may form in a fire involving aluminum nitrate.
Reactivity
Nitrates and nitrites may act as extremely potent oxidizing agents and mixtures with reducing agents or reduced materials such as organic substances may be explosive. Reacts with acids to form toxic nitrogen dioxide.
In general, nitrate and nitrite salts with active redox cations (transition metals and the metals of groups 3a, 4a and 5a of the periodic table, as well as the ammonium cation [NH4] +) are more reactive with organic materials and agents Reducers under environmental conditions.
Aluminum nitrate is an oxidizing agent. Mixtures with alkyl esters may explode. Mixtures with phosphorus, tin (II) chloride or other reducing agents may react explosively.
Toxicity
Humans are subject to the toxicity of nitrates and nitrites, with children being especially vulnerable to methemoglobinemia.
Ingestion of large doses of aluminum nitrate causes gastric irritation, nausea, vomiting, and diarrhea. Contact with the powder irritates the eyes and skin.
Applications
Nitrates and nitrites are widely used (and in very large amounts) as fertilizers in agriculture because of their willingness to decompose and release nitrogen for plant growth and because of their solubility, which allows nitrate ions to be Absorbed by the roots of the plant.
Nitrate compounds are also widely used as an industrial feedstock when an oxidizing agent or a nitrate ion source is required.
Aluminum nitrate is used in the manufacture of laboratory chemicals, cosmetics and personal hygiene. In industry, it is used as intermediates in the manufacture of other substances.
It is used in tanning leather, antiperspirants, corrosion inhibitors, uranium extraction, petroleum refining, and as a nitrating agent.
Nonahydrated aluminum nitrate and other hydrated aluminum nitrates have many applications. These salts are used to produce alumina for the preparation of insulation papers, heating elements of the cathode ray tubes and the core laminates of the transformers. Hydrated salts are also used for the extraction of actinic elements.
Clinical effects
Aluminum is ubiquitous, the most abundant metal in the earth's crust. Most human exposure comes from food. It is present in some pharmaceutical products. In the industry is widely used.
Aluminum inhibits bone remodeling, causing osteomalacia. It is thought to inhibit erythropoiesis, causing anemia.
Acute intoxication is rare. The soluble forms of aluminum have a greater potential of toxicity than the insoluble forms, due to their greater absorption.
Patients with renal impairment are prone to the toxicity of aluminum, either from aluminum in the dialysate or other exogenous sources, especially phosphate binders and aluminum-containing antacids.
Chronic exposure to aluminum dust may cause dyspnoea, cough, pulmonary fibrosis, pneumothorax, pneumoconiosis, encephalopathy, weakness, incoordination, and epileptiform seizures.
Aluminum salts can cause irritation of the eyes and mucous membranes, conjunctivitis, dermatosis and eczema.
Although aluminum and its compounds have shown little evidence of carcinogenicity in humans, exposure to other substances involved in aluminum production has been linked to carcinogenicity.
Safety and risks
Hazard statements of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an internationally agreed system, created by the United Nations and designed to replace the various classification and labeling standards used in different countries through the use of globally consistent criteria.
The hazard classes (and their corresponding GHS chapter), the classification and labeling standards, and the recommendations for aluminum nitrate and aluminum nitrate nonahydrate are as follows (European Chemicals Agency, 2017; United Nations, 2015; PubChem, 2017):
GHS Hazard Classes
H272: May intensify fire; Oxidant [Warning Oxidising Liquids; Oxidizing Solids - Category 3] (PubChem, 2017).
H301: Toxic if swallowed [Danger Acute Toxicity, oral - Category 3] (PubChem, 2017).
H315: Causes skin irritation [Warning Skin corrosion / irritation - Category 2] (PubChem, 2017).
H318: Causes serious eye damage [Danger Serious eye damage / eye irritation - Category 1] (PubChem, 2017).
H319: Causes serious eye irritation. [Warning Serious eye damage / eye irritation - Category 2A] (PubChem, 2017).
