We frequently define an acid or a base as a substance whose aqueous solution gives, respectively, a higher concentration of hydrogen ion or of hydroxide ion than that furnished by pure water. This is a very one sided definition. Gilbert N. Lewis

Structural chemistry The hydroxide ion appears to rotate freely in crystals of the heavier alkali metal hydroxides at higher temperatures so as to present itself as a spherical ion, with an effective ionic radius of about 153 pm. Source: Internet

However, this transformation is not 100% complete, and invariably leaves residual amounts of hydroxide ion from NaOH. Source: Internet

Solutions containing the hydroxide ion are generated when a salt of a weak acid is dissolved in water. Source: Internet

The hydroxide ion forms salts, some of which dissociate in aqueous solution, liberating solvated hydroxide ions. Source: Internet

This arrangement led to the suggestion that there are directional bonds between OH groups in adjacent layers. citation This is an unusual form of hydrogen bonding since the two hydroxide ion involved would be expected to point away from each other. Source: Internet
