Zinc dissolves in water as ZnOH+(aq) or Zn2+(aq). Anionic ZnCO3has a solubility of 0.21 g/L. Examples of solubility of zinc compounds are: zinc chloride (ZnCl2) 4320 g/L, and zinc oxide (ZnO) or zinc vitriol (ZnSO4. 7H2O) 580 g/L Why is zinc present in water?

These findings suggested that compared with the migration behavior of Cd, Pb, and Zn, that of As has a farther-reaching impact on agricultural soils owing to its geochemical cycling in the soil and groundwater environment. This impact differed significantly in magnitude from that of the other investigated metals.
