  • A hydroxide attached to a strongly electropositive center may itself ionize,[citation needed] liberating a hydrogen cation (H+), making the parent compound an acid. (wikipedia.org)
  • Addition of a base to water will reduce the hydrogen cation concentration and therefore increase the hydroxide ion concentration (increase pH, decrease pOH) even if the base does not itself contain hydroxide. (wikipedia.org)

  • Thus it will dissolve readily in a dilute solution of a strong acid, such as HCl, and also in a solution of an alkali such as sodium hydroxide. (wikipedia.org)
  • Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium sulfate, or magnesium sulfate). (wikipedia.org)
  • Sodium hydroxide is completely ionic, containing sodium cations and hydroxide anions. (vias.org)
  • Layered double hydroxides (LDH) are a class of ionic solids characterized by a layered structure with the generic layer sequence [AcBZAcB]n, where c represents layers of metal cations, A and B are layers of hydroxide (HO− ) anions, and Z are layers of other anions and neutral molecules (such as water). (wikipedia.org)
  • As one of the simplest hydroxides, it is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students. (wikipedia.org)
