Knowra Zinc hydroxide Zinc hydroxide Zinc hydroxide, Zn(OH)₂, is an inorganic compound that forms from zinc ions and hydroxide ions. It is amphoteric, dissolving in acids and strong bases.
Amphoterism : The ability of a substance to react as either an acid or a base, depending on its chemical environment. Zinc hydroxide displays amphoterism by reacting with both acids and strong bases.
Zinc : A metallic chemical element with atomic number 30 and symbol Zn. Zinc hydroxide is one of zinc's inorganic compounds.
Zinc oxide : An inorganic compound, ZnO, used in ceramics, coatings, sunscreens, and other materials. Heating zinc hydroxide can produce zinc oxide and water.
Aluminium hydroxide : An amphoteric inorganic compound, Al(OH)₃, that dissolves in acids and strong bases. It shares zinc hydroxide's amphoterism but has different metal-centered chemistry.
Zincate : An anionic zinc species formed when zinc compounds dissolve in strongly alkaline solution. Excess hydroxide converts zinc hydroxide into soluble zincate species.
Ionic compound : A compound composed of positively and negatively charged ions held together by electrostatic attraction. Its formula combines zinc cations and hydroxide anions in a charge-balanced solid.
Zinc hydroxide battery : An electrochemical cell or battery system in which zinc hydroxide participates in electrode reactions. Zinc hydroxide can occur as a reaction product in alkaline zinc electrodes.
Magnesium hydroxide : An inorganic compound, Mg(OH)₂, that is sparingly soluble in water and primarily basic. Unlike zinc hydroxide, it does not readily dissolve in excess strong base.
Hydroxide ion : The negatively charged polyatomic ion OH⁻, consisting of one oxygen atom bonded to one hydrogen atom. Hydroxide ions combine with Zn²⁺ to form zinc hydroxide.
Acid–base reaction : A chemical reaction involving transfer of protons or formation of conjugate acid–base species. Its dissolution in acid consumes hydroxide through protonation.
