Science / Chemistry / Autoprotolysis: Transfer of a hydrogen ion between molecules of the same substance, e. g. the autoprotolysis of methanol (2 CH3OH = CH3OH2+ + CH3O-). Autoprotolysis of water into hydronium ions and hydroxide ions results in equilibrium concentrations that satisfy Kw = [H3O+][OH-], where the autoprotolysis constant Kw is equal to 1.01 × 10-14 at 25°C.


Science / Chemistry / Kw: Symbol for the autoprotolysis constant for water, equal to 1.01 × 10-14 at 25°C. MORE

Aprotic Solvent

Science / Chemistry / Aprotic Solvent: A solvent that does not act as an acid or as a base; aprotic solvents don't undergo autoprotolysis. Examples are pentane, pet ether, and toluene. MORE

Amphiprotic Solvent

Science / Chemistry / Amphiprotic Solvent: Solvents that exhibit both acidic and basic properties; amphiprotic solvents undergo autoprotolysis. Examples are water, ammonia, and ethanol. MORE
