Cossorion, in general, is a process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides. Likewise, the rusting of iron involves the formation of iron oxides via the action of atmospheric moisture and oxygen. If we look at the science behind corrosion, then we can say ...
The sodium hydroxide, calcium carbonate and potassium oxide are examples of bases. A base is a substance that reacts with hydrogen ions and can neutralize the acid. Most bases are minerals which form water and salts by reacting with acids. Bases include the metal oxides, hydroxides, and carbonates. Q8.
Corrosion is the mechanism by which metals that have been processed revert to their normal oxidation states. This is a reduction-oxidation reaction in which the metal is oxidized by its environment, which is usually oxygen in the air. This reaction is favoured both electrochemically and spontaneously. Q2.
Erosion is a physical process. Corrosion is a chemical process. Occurs on the surface of the land. Occurs on the surface of materials like polymers, ceramics or metals. Natural agents like water, gravity, wind, causes erosion. Corrosive agents such as oxygen, sulfates can cause corrosion. Erosion involves different processes like transportation ...
Fe3+ + 3OH– → Fe (OH)3. The resulting hydroxides of iron now undergo dehydration to yield the iron oxides that constitute rust. This process involves many chemical reactions, some of which are listed below. Fe (OH) 2 ⇌ FeO + H 2 O. 4Fe (OH) 2 + O 2 + xH 2 O → 2Fe 2 O 3. (x+4)H 2 O. Fe (OH) 3 ⇌ FeO (OH) + H 2 O.
Organic acids – Organic acids are corrosive and toxic. Corrosivity is a form of toxicity to the tissues that the acid contacts. Organic acids and their derivatives cover a wide range of substances. They are used in nearly every type of chemical manufacture. Because of the variety in the chemical structure of the members of the organic acid group.
Sodium hydroxide (NaOH) - Sodium hydroxide is an ionic compound. The molecular weight of sodium hydroxide is 40 g/mol. It is a white, translucent crystalline solid and used in the manufacturing of detergents and soaps.

Name the types of corrosion inhibitors. Ans: There are three types of corrosion inhibitors. They are: Cathodic Inhibitor. Anodic Inhibitor. Mixed Inhibitor. 2. Define anodic inhibitors. Ans: A inhibitor which forms a protective oxide film on metal’s surface and causes an anodic shift of the corrosion potential is defined as an anodic inhibitor.
Alkali is a base. It is a base that dissolves in water. This is very important to remember-. Not all bases are alkali but all alkali is base. It is a basic salt alkali earth metal or alkali metal. On adding alkali to acid the pH of the mixture increase. On adding acid to alkali the pH decreases due to the removal of alkali.
Acid rain is made up of highly acidic water droplets due to air emissions, most specifically the disproportionate levels of sulphur and nitrogen emitted by vehicles and manufacturing processes. It is often called acid rain as this concept contains many types of acidic precipitation. The acidic deposition takes place in two ways: wet and dry.
