About Sodium Nitrate Solution

Nitrate IonSodium Nitrate Solutions are moderate to highly concentrated liquid solutions of Sodium Nitrate. They are an excellent source of Sodium Nitrate for applications requiring solubilized Compound Solutions Packaging, Bulk Quantity materials. American Elements can prepare dissolved homogeneous solutions at customer specified concentrations or to the maximum stoichiometric concentration. Packaging is available in 55 gallon drums, smaller units and larger liquid totes. American Elements maintains solution production facilities in the United States, Northern Europe (Liverpool, UK), Southern Europe (Milan, Italy), Australia and China to allow for lower freight costs and quicker delivery to our customers. American Elements metal and rare earth compound solutions have numerous applications, but are commonly used in petrochemical cracking and automotive catalysts, water treatment, plating, textiles, research and in optic, laser, crystal and glass applications. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Sodium Nitrate Powder. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.

It is the seventh most abundant element in the universe and it constitutes 78.09% (by volume) of Earth's atmosphere. Nitrogen was discovered by Daniel Rutherford in 1772.


Sodium Bohr ModelSee more Sodium products. Sodium (atomic symbol: Na, atomic number: 11) is a Block D, Group 5, Period 4 element with an atomic weight of 22.989769. The number of electrons in each of Sodium's shells is [2, 8, 1] and its electron configuration is [Ne] 3s1. The sodium atom has a radius of 185.8 pm and a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silvery-white metallic appearance. It is the sixth most abundant element, making up 2.6 % of the earth's crust. Sodium does not occur in nature as a free element and must be extracted from its compounds (e.g., feldspars, sodalite, and rock salt). The name Sodium is thought to come from the Arabic word suda, meaning "headache" (due to sodium carbonate's headache-alleviating properties), and its elemental symbol Na comes from natrium, its Latin name.
