The nitrate can be easily replaced by other ligands, rendering AgNO 3 versatile. Finally, it dissolves in numerous solvents, including water. It is non- hygroscopic, in contrast to silver fluoroborate and silver perchlorate. Silver nitrate is the least expensive salt of silver it offers several other advantages as well. Uses Precursor to other silver compounds Most metal nitrates thermally decompose to the respective oxides, but silver oxide decomposes at a lower temperature than silver nitrate, so the decomposition of silver nitrate yields elemental silver instead. Qualitatively, decomposition is negligible below the melting point, but becomes appreciable around 250 ☌ and fully decomposes at 440 ☌.

The silver nitrate reacts with copper to form hairlike crystals of silver metal and a blue solution of copper nitrate:Ģ AgNO 3(l) → 2 Ag(s) + O 2(g) + 2 NO 2(g) Ī typical reaction with silver nitrate is to suspend a rod of copper in a solution of silver nitrate and leave it for a few hours. The Ag-O distances range from 2.384 to 2.702 Å. Each Ag + center is bonded to six oxygen centers of both uni- and bidentate nitrate ligands. In the common orthorhombic form stable at ordinary temperature and pressure, the silver atoms form pairs with Ag-Ag contacts of 3.227 Å. The structure of silver nitrate has been examined by X-ray crystallography several times. The stoichiometry of the reaction depends upon the concentration of nitric acid used.ģ Ag + 4 HNO 3 (cold and diluted) → 3 AgNO 3 + 2 H 2O + NO Ag + 2 HNO 3 (hot and concentrated) → AgNO 3 + H 2O + NO 2 Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. 3.1 Precursor to other silver compoundsĪlbertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver.Please let us know how we can improve this web app. Related: Molecular weights of amino acids

Weights of atoms and isotopes are from NIST article. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass) Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg.Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
