The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
Anhydrous iron(III) fluoride is prepared by treating virtually any anhydrous iron compound with fluorine. More practically and like most metal fluorides, it is prepared by treating the corresponding chloride with hydrogen fluoride: [7] FeCl 3 + 3 HF → FeF 3 + 3 HCl
Aside from lability, which applies to anhydrous and hydrated forms, the reactivity of anhydrous ferric chloride reveals two trends: It is a Lewis acid and an oxidizing agent. [20] Reactions of anhydrous iron(III) chloride reflect its description as both oxophilic and a hard Lewis acid. Myriad manifestations of the oxophiliicty of iron(III ...
To prevent this, anhydrous solvents must be used when performing certain reactions. Examples of reactions requiring the use of anhydrous solvents are the Grignard reaction and the Wurtz reaction. Solvents have typically been dried using distillation or by reaction with reactive metals or metal hydrides. These methods can be dangerous and are a ...
Tetrahydrofuran (THF) dissolves alkali metal, but a Birch reduction (see § Applications) analogue does not proceed without a diamine ligand. [8] Solvated electron solutions of the alkaline earth metals magnesium, calcium, strontium and barium in ethylenediamine have been used to intercalate graphite with these metals. [9]
Salts have long had a wide variety of uses and applications. Many minerals are ionic. [ 82 ] Humans have processed common salt (sodium chloride) for over 8000 years, using it first as a food seasoning and preservative, and now also in manufacturing, agriculture , water conditioning, for de-icing roads, and many other uses.

Such solutions are less toxic than bromoform and methylene iodide, but still have densities that fall between a number of naturally coupled minerals. [ 4 ] Sodium tungstate is a competitive inhibitor of molybdenum ; because tungsten is directly below molybdenum on the periodic table, it has similar electrochemical properties.
