The series of chemical reactions starting with zinc (Zn) and ending with zinc chloride (ZnCl2) involves the following steps:
Zinc reacts with oxygen in the air to form zinc oxide (ZnO):Zn + O2 → ZnO
Zinc oxide reacts with nitric acid (HNO3) to form zinc nitrate (Zn(NO3)2):ZnO + 2HNO3 → Zn(NO3)2 + H2O
Zinc nitrate reacts with sodium hydroxide (NaOH) to form zinc hydroxide (Zn(OH)2):Zn(NO3)2 + 2NaOH → Zn(OH)2 + 2NaNO3
Zinc hydroxide reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl2):Zn(OH)2 + 2HCl → ZnCl2 + 2H2O
So, the overall reaction pathway is:Zn → ZnO → Zn(NO3)2 → Zn(OH)2 → ZnCl2
