28 cze 2024 · Reaction with Acids: Zinc reacts with dilute acids, releasing hydrogen gas and forming zinc salts. Equation (with hydrochloric acid): 2Zn+2HCl→ZnCl₂+H₂; Reaction with Alkalis: Zinc reacts with strong bases, forming zincates and releasing hydrogen gas. Equation (with sodium hydroxide): 2Zn+2NaOH+2H₂ O→Na₂ [Zn(OH)₄ ]+H₂
24 mar 2021 · Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals (e.g., nitric acid with magnesium, manganese or zinc will liberate \(\ce{H2}\) gas): \[\ce{Mg + 2 HNO3 → Mg(NO3)2 + H2 }\]
metal oxide + acid → a salt + water. The salt made depends on the metal oxide and the acid used. For example, copper chloride is made if copper oxide and hydro chloric acid are used:

20 kwi 2023 · Dilute nitric acid behaves as a typical acid in its reaction with most metals. For example, magnesium, manganese, and zinc liberate hydrogen gas: Mg (s) + 2 HNO 3 (aq) → Mg (NO 3) 2 (aq) + H 2 (g) Mn (s) + 2 HNO 3 (aq) → Mn (NO 3) 2 (aq) + H 2 (g) Zn (s) + 2 HNO 3 (aq) → Zn (NO 3) 2 (aq) + H 2 (g)
Zinc reacts with alkalis as with acids. With oxidants such as chalcogens and halogens, Zn forms binary compounds such as ZnS and ZnCl 2. Zinc oxide, ZnO, is the most important manufactured compound of zinc, with a wide variety of uses. [2] . It crystallizes with the Wurtzite structure.
The second largest use of zinc is in making alloys. An alloy is made by melting and mixing two or more metals. The mixture has properties different from those of the individual metals. Two of the most common alloys of zinc are brass and bronze. Brass is an alloy of zinc and copper.
