CBSE Class 10th Corrosion and its Prevention & Preparations Downloads
Two main classes of elements are distinguished from one another by their physical and chemical characteristics. Metals and nonmetals are these two categories of elements. When oxygen and moisture are present in the atmosphere, chemically active metals corrode. Higher reactivity metals (including zinc, iron, magnesium, and tin) are far more prone to corrosion.
A refined substance can naturally undergo corrosion to change into a more chemically stable state, such as its oxide, hydroxide, or sulfide. It is the instantaneous breakdown of a substance (usually a metal) as a result of environmental chemical and/or electrochemical processes. The beneficial qualities of metal and buildings, such as their strength, appearance, and permeability to liquids and gasses, are eroded by corrosion. The breakdown of metals due to a chemical reaction occurring in the
