Zn 2+ + 2 OH − → Zn(OH) 2. The initial colorless solution contains the zincate ion: Zn(OH) 2 + 2 OH − → Zn(OH) 4 2−. Zinc hydroxide will dissolve because the ion is normally surrounded by water ligands; when excess sodium hydroxide is added to the solution the hydroxide ions will reduce the complex to a −2 charge and make it soluble.

Another factor determining the size of a keyboard is the size and spacing of the keys. The reduction is limited by the practical consideration that the keys must be large enough to be easily pressed by fingers.
In its compounds, Zn 2+ ions have an electronic configuration [Ar] 3d 10.As such, Zn 2+ tends to have a symmetrical coordination geometry in both its complexes and compounds. In both ZnO and ZnS, zinc is bound tetrahedrally bound to four ligands (oxide and sulfide, respectively).
