The hydroxide ion by by itself just isn't a solid more than enough foundation, but it could be transformed to one by adding sodium hydroxide to ethanol
It may also act as a Lewis foundation by donating a set of electrons to some Lewis acid. In aqueous Alternative the two hydrogen ions and hydroxide ions are strongly solvated, with hydrogen bonds concerning oxygen and hydrogen atoms. Certainly, the bihydroxide ion H
