The free radicals generated by this process engage in secondary reactions. For example, the hydroxyl is a powerful, non-selective oxidant. [6] Oxidation of an organic compound by Fenton's reagent is rapid and exothermic and results in the oxidation of contaminants to primarily carbon dioxide and water.
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known.
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.
Iron(III) sulfate (or ferric sulfate), is a family of inorganic compounds with the formula Fe 2 (SO 4) 3 (H 2 O) n.A variety of hydrates are known, including the most commonly encountered form of "ferric sulfate".
This process is described by the Schikorr reaction: 3 Fe(OH) 2 → Fe 3 O 4 + H 2 + 2 H 2 O. Anions such as selenite and selenate can be easily adsorbed on the positively charged surface of iron(II) hydroxide, where they are subsequently reduced by Fe 2+. The resulting products are poorly soluble (Se 0, FeSe, or FeSe 2).
Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. [1] Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis .
(The Center Square) – President-elect Donald Trump has made international headlines by suggesting that Canada could become the 51st state and the U.S. could purchase Greenland. U.S. expansionist ...
A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry. It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by atom or group. [1] [2] [3] It can be represented generically as: + +
