1. Reaction occurs.
Like other carbonates, zinc carbonate reacts with hydrochloric acid to give zinc chloride solution, carbon dioxide gas and water.
ZnCO₃ + 2HCl → ZnCl₂ + H₂O + CO₂
2. Reaction occurs.
Zinc hydroxide is a base which neutralizes hydrochloric acid.
Zn(OH)₂ + 2HCl → ZnCl₂ + 2H₂O
3. Reaction occurs.
Zinc is a reactive metal which reacts with hydrochloric acid to give hydrogen gas.
Zn + 2HCl → ZnCl₂ + H₂
4. There is no reaction.
Zinc nitrate does not undergo neutralization, gas formation, redox reaction, or other reaction with hydrochloric acid.
