The equation for the formation of zinc ions (Zn2+) can be represented as follows:
Zn(s) → Zn2+(aq) + 2e-
This equation shows the oxidation of solid zinc to form zinc ions in aqueous solution. The zinc atoms lose two electrons to become positively charged zinc ions.
On the other hand, the equation for the formation of carbonate ions (CO32-) can be represented as follows:
CO2(g) + H2O(l) → H2CO3(aq) → H+(aq) + HCO3-(aq) → 2H+(aq) + CO32-(aq)
This series of reactions shows the dissolution of carbon dioxide in water to form carbonic acid, which then dissociates to form hydrogen ions and bicarbonate ions. Further dissociation of the bicarbonate ions results in the formation of carbonate ions.
When zinc ions and carbonate ions come into contact, they can react to form zinc carbonate. The balanced chemical equation for this reaction is:
Zn2+(aq) + CO32-(aq) → ZnCO3(s)
In this reaction, the zinc ions combine with the carbonate ions to form solid zinc carbonate. This reaction is a precipitation reaction, where a solid product is formed from the mixing of two aqueous solutions containing the respective ions.

Equations involving zinc ions (Zn²⁺) and carbonate ions (CO₃²⁻)
1. Formation of zinc carbonate precipitate:
Zn²⁺ + CO₃²⁻ → ZnCO₃(s)
2. Dissolution of zinc carbonate in excess carbonate ions (forming the zinc carbonate complex):
ZnCO₃(s) + CO₃²⁻ → [Zn(CO₃)₄]²⁻
3. Precipitation of zinc hydroxide under alkaline conditions:
Zn²⁺ + 2OH⁻ → Zn(OH)₂(s)
4. Dissolution of zinc hydroxide in excess hydroxide ions (forming the zincate complex):
Zn(OH)₂(s) + 2OH⁻ → [Zn(OH)₄]²⁻
5. Precipitation of zinc sulfide under alkaline conditions:
Zn²⁺ + S²⁻ → ZnS(s)
6. Dissolution of zinc sulfide in excess sulfide ions (forming the zinc sulfide complex):
ZnS(s) + S²⁻ → [Zn(S)₄]⁴⁻
Note: The solubility of zinc carbonate is significantly affected by pH. At high pH, the formation of the zinc carbonate complex increases its solubility. Conversely, at low pH, the precipitation of zinc carbonate is favored.
