Salt metathesis is a common technique for exchanging counterions. The choice of reactants is guided by a solubility chart or lattice energy. HSAB theory can also be used to predict the products of a metathesis reaction. Salt metathesis is often employed to obtain salts that are soluble in organic solvents.
The low solubility of KClO 3 in water causes the salt to conveniently isolate itself from the reaction mixture by simply precipitating out of solution. Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3
The distinctive feature of the Grignard reagents is their formation from the organic halide and magnesium metal. Most other group II organic compounds are generated by salt metathesis, which limits their accessibility. The formation of the Grignard reagents has received intense scrutiny.
Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. [4] It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid. [2]
Using salt metathesis reactions, nitrite, azide, and other small inorganic anions can be obtained with [(Ph 3 P) 2 N] + cations. The resulting salts [(Ph 3 P) 2 N] + NO − 2, [(Ph 3 P) 2 N] + N − 3, etc. are soluble in polar organic solvents. [(Ph 3 P) 2 N] + forms crystalline salts with a range of anions that are otherwise difficult to ...
Metathesis (linguistics), alteration of the order of phonemes within a word Quantitative metathesis , exchange of long and short roles, without changing order of vowel sounds Chemical change in which a pair of molecules exchange electronic patterns of bonding
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral).
