In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide. Once all of the copper has reacted, the solution is diluted with distilled water, changing … This reaction generates the very flammable element H2, or hydrogen gas. The metals Cu and Zn in brass react with dil. Dilute nitric acid act as a typical acid when it reacts with a reactive metals such as sodium, magnesium, zinc and more. Aluminum and zinc do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults. Copper solid does not react with hydrochloric acid but does with nitric acid. 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. You can change your choices at any time by visiting Your Privacy Controls. The re­ac­tion of cop­per with ni­tric acid takes place in two stages: at the first stage, the acid ox­i­dizes the cop­per to cop­per ox­ide, re­leas­ing ni­tro­gen diox­ide; at the sec­ond stage, cop­per ox­ide re­acts with new por­tions of acid, form­ing cop­per ni­trate Cu (NO₃)₂. Zinc, however, reacts with diluted nitric acid (for an analog, see Experiment 4.4.24.1).

Citric acid also cleans copper. In rainy season, brass gets corroded because copper in brass reacts with oxygen, carbon dioxide and moisture present in the atmosphere to form basic copper carbonate. Write down the changes that will be seen in the instance and explain the reason behind it. Nitric acid is a strong oxidizing agent, so often it exhibits both acidic and oxidizing behavior when reacting with a metal. Zinc, however, reacts with diluted nitric acid (for an analog, see Experiment 4.4.24.1). Metals and dilute nitric acid reaction. Any acid works by donating Hydrogen to evolve water -- in the case of Nitric acid, the metal causes the nitric acid to break down into Hydrogen and nitrate ions which then combine with the copper to make copper nitrate, Nitrogen dioxide and water. For the cases of zinc and copper, no hydrogen gas molecules are released to the surroundings.
