Zinc carbonate (ZnCO₃) is considered a basic salt. It can react with acids to produce zinc salts, carbon dioxide, and water, indicating its basic properties. In aqueous solutions, it can partially dissociate to release carbonate ions, which can neutralize acids. Therefore, while it has basic characteristics, it is not a strong base like sodium hydroxide.
Zinc carbonate and nitric acid react to form zinc nitrate, carbon dioxide gas, and water. This is a typical acid-base reaction where the carbonate ion reacts with the acid to form a salt, carbon dioxide, and water.
zinc carbonate + sulphuric acid = zinc sulphate + water + carbon dioxide
When zinc carbonate is added to sulfuric acid, a chemical reaction takes place where zinc sulfate, carbon dioxide, and water are formed. The zinc carbonate will dissolve in the sulfuric acid, releasing carbon dioxide gas and forming zinc sulfate solution. This reaction is a typical neutralization reaction between an acid and a base.
You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.
ZnCO3 + 2HNO3 ----> Zn(NO3)2 + H2O + CO2
Zinc hydroxide plus carbonic acid yields zinc carbonate plus water
ZnCO3 is zinc carbonate, aka smithsonite, which is neither an acid nor a base, but rather a salt.
you can use the hydrochloric acid to differentiate between the zinc carbonate and zinc chloride as the zinc carbonate will give effervescence and the gas produced (carbon dioxide) turns lime water milky..and the zinc chloride will give no ppt
Sodium Carbonate is a base.
Hydrogen Chloride gas --> HCl or Hydrochloric Acid --> HCl(aq)
Silver carbonate is a CHEMICAL SALT. Hence it is neither an acid nor a base.
Examples of carbonates are damaged by acid rain are sodium carbonate, magnesium carbonate, and zinc carbonate.
