Download PDF zinc (zn) Chemical Reactions class 12
Welcome back to our blog post today we are going to talk about all the important Zinc reactions in class 12th so if you are a class 12th student and learning chemistry then you can use this post because in this article you can find all the ZINC-related reactions in one place.
Properties of zinc
Before we check the reaction let's talk about the properties:
Property | Description |
---|---|
Atomic Symbol | Zn |
Atomic Number | 30 |
Atomic Mass | 65.38 amu |
Electron Configuration | [Ar] 3d10 4s2 |
Melting Point | 419.5°C |
Boiling Point | 907°C |
Density | 7.14 g/cm³ |
Oxidation States | +2 |
Reactivity | Reacts with acids to produce hydrogen gas. Forms oxides when heated in air. |
Corrosion Resistance | Zinc exhibits excellent corrosion resistance and is commonly used as a protective coating. |
Alloy Formation | Forms alloys with other metals such as copper (brass) and aluminum (zinc-aluminum alloy). |
Reducing Agent | Can act as a reducing agent in certain chemical reactions, such as with copper oxide. |
Formation of Compounds | Forms various compounds such as zinc chloride (ZnCl2), zinc sulfate (ZnSO4), and zinc oxide (ZnO). |
Amphoteric Nature | Exhibits an amphoteric nature, meaning it can react with both acids and bases. |
Now before let's check out the reaction:
zinc (zn) Chemical Reactions
Reaction Description | Chemical Equation | Interpretation |
---|---|---|
Zinc and Hydrochloric Acid (HCl) | Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas. | |
Zinc and Sulfuric Acid (H2SO4) | Zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas. | |
Zinc Oxide (ZnO) and Hydrogen Gas (H2) | Zinc oxide reacts with hydrogen gas to produce zinc and water vapor. | |
Zinc and Copper(II) Sulfate (CuSO4) Solution | Zinc displaces copper from copper sulfate solution to form zinc sulfate and copper metal. | |
Zinc and Nitric Acid (HNO3) | Zinc reacts with nitric acid to produce zinc nitrate, nitrogen dioxide gas, and water. | |
Zinc and Oxygen (Combustion Reaction) | Zinc reacts with oxygen in the air during combustion to form zinc oxide. |
