Source: quora.com. Despite the fact that your stomach produces hydrochloric acid, the zinc in food and supplements doesn't react with stomach acid, because the zinc is not in elemental form. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. The rate of reaction can be compared by means of the rate of production of hydrogen gas bubbles. 7 years ago. While not all metals react with hydrochloric acid, or HCl, some do. At just about any concentration it will react to form H2 gas. For reactions that produce gases: gas syringes or collection over water can be used to measure the volume of gas produced; mass change can be followed using a balance, C6.2.11 draw and interpret appropriate graphs from data to determine rate of reaction, C6.2.12 determine gradients of graphs as a measure of rate of change to determine rate. Zinc is an electropositive element. Aluminium does not react with water, because it forms a tough protective layer of aluminium oxide, "Al"_2"O"_3, on its surface. 0 0. In test tube 3, zinc displaces copper from the copper sulfate solution and the surface of the zinc goes black. In test tube 2, copper is the catalyst for the reaction, and the reaction should be faster than in test tube 1, but may not be as fast as test tube 3. Does Zinc React With Hydrochloric Acid? star. Zn (s) + H2SO4 (aq) ---> ZnSO4 (aq) + H2 (g) Here is a video of this reaction -. Reaction of zinc with acids. When hydrochloric acid and zinc are combined, they create hydrogen gas and zinc chloride, which is a salt. Strong acids react by oxidizing a metal, changing a pure elemental metal into a metal oxide. Answer With cold, dilute nitric acid, zinc liberates nitric oxide ( N O ), along with soluble zinc nitrate and water. zinc is an exception it makes amphoteric oxides:these oxides react with both acids and bases other than zinc aluminium tin and lead also react with bases.
