1931N. F. Hall in Chem. Rev. VIII. 191 Acid-base or protolytic reaction may be defined by the general equation..A {equil} B + {earth} (acid {equil} base + proton). 1934Chem. Abstr. XXVIII. 5740 Acids and bases are designated [by J. N. Brønsted] ‘protolyte’ and their reaction ‘protolysis’. 1959I. M. Kolthoff in Kolthoff & Elving Treat. Analytical Chem. I. i. xi. 411 It is clear that a base can be of any charge type, its charge being one less positive than that of its conjugate acid, for example, Al(OH)2+, NH3, HCO3-, CO3- 2. Its reaction with an acid solvent is called a protolysis reaction and no distinction is made between a dissociation (NH3 in water) and hydrolysis (cyanide in water). 1968V. Gutmann Coordination Chem. in Non-Aqueous Solutions i. 6 Acids and bases are defined as proton donors and proton acceptors respectively and acidbase reactions are regarded as being due to proton transfer reactions (protolysis). 1969T. R. Blackburn Equilibrium ii. 66 If a solvent is both appreciably acid and appreciably basic (as water is), it will have a measurable autoprotolysis constant. Such solvents are called protolytic. |
