This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. Elemental zinc reacts with strong bases forming hydrogen: Zn (s) + 2 OH − (aq) Zn(OH) 2 (s) + H 2 (g) Zn 2+ is precipitated by hydroxide ions as Zn(OH) 2 (white amorphous precipitate) [1] Zn 2+ (aq) + 2 OH − (aq) Zn(OH) 2 (s) By acid excess hydroxide, the precipitate is dissolved [1] Zn(OH) 2 (s) + 2 H + (aq) Zn 2+ (aq) + 2 H 2 O (l) Zn(OH) 2 (s) + 2 OH − (aq) [Zn(OH) 4] 2− (aq) Naming and Formulas for Ionic Compounds Ionic compounds are formed between oppositely charged ions usually consisting of a metal and one or more non-metals. An ion can be a single charged atom or a small group of atoms (molecule) with a charge.
