Preferred Label : autoprotolysis constant;
IUPAC definition : The product of the activities (or, more approximately, concentrations) of the species
produced as the result of autoprotolysis. For solvents in which no other ionization
processes are significant the term is synonymous with 'ionic product'. The autoprotolysis
constant for water, Kw, is equal to the product of activities: \[a\left({H}_{3}{O}
{{ }}\right)\ a\left({OH} {{-}}\right) 1.0\times 10 {-14}\] at 25 C.;
