In weak basic solutions containing Zn2+ ions, the hydroxide Zn(OH)
2 forms as a white precipitate. In stronger alkaline solutions, this hydroxide is dissolved to form zincates ([Zn(OH)4]2−). The nitrate Zn(NO3)
2, chlorate Zn(ClO3)
2, sulfate ZnSO
4, phosphate Zn
3(PO4)
2, molybdate ZnMoO
4, cyanide Zn(CN)
2, arsenite Zn(AsO2)
2, arsenate Zn(AsO4)
2·8H
2O and the chromate ZnCrO
4 (one of the few colored zinc compounds) are a few examples of other common inorganic compounds of zinc. One of the simplest examples of an organic compound of zinc is the acetate (Zn(O
2CCH3)
2).

Zn(OH)2 is dissolved to form what in strong alkaline solutions?
