Put a few pieces of granulated zinc into each of the three test tubes. Zinc, catalysed by copper, reacts with sulfuric acid. I would argue that Carbonic acid is not a sufficient reducing agent to reduce zinc to its +2 oxidation state. This will occur until the hydrogen from the acid has balanced with what the reaction. This is an experiment from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry. To perform this experiment, a scientist begins by adding a small amount of hydrochloric acid to a Petri dish or a flask. Since the zinc is oxidized and the reaction needs to remain balanced, the hydrogen atoms are reduced. Zn(s) + H 2 SO 4 (g) → ZnSO 4 (s) + H 2 (Zinc) (dil.

Zn(s) + H 2 SO 4 (aq) -----> ZnSO 4 (aq) + H 2 (g) It is clear that Zn displaces Hydrogen from sulphuric acid. A metal's ability to react with HCl depends upon the metal's so-called activity, where metals with high activity react with HCl. But Zinc cotted with copper (like coin) doesnot react to acid.The thin copper cladding prevents the zinc from reacting.Copper itself does not react with hydrochloric acid, and so does not break down and allow the acid to react with the zinc.So the coin does not react because it is 'protected' by a layer of nonreactive copper. Zinc is more reactive than hydrogen. Bubbles of hydrogen form on the surface of the zinc. star. A metal's ability to react with HCl depends upon the metal's so-called activity, where metals with high activity react with HCl.
