ZnCO3 is zinc carbonate, aka smithsonite, which is neither an acid nor a base, but rather a salt.
zinc carbonate + sulphuric acid = zinc sulphate + water + carbon dioxide
Zinc hydroxide plus carbonic acid yields zinc carbonate plus water
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
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.
Smithsonite
Sodium Carbonate is a base.
Its a acid base simply acid ;)
It is a base.
it is a base
Examples of carbonates are damaged by acid rain are sodium carbonate, magnesium carbonate, and zinc carbonate.
