Iron oxides are iron and oxygen-containing chemical compounds. Rust, a type of iron(III) oxide, is the most well-known of the sixteen known iron oxides and oxyhydroxides. Iron oxides are common compounds found in nature that can be easily synthesised in the laboratory. Magnetic iron oxides have been used by humans for centuries; for example, small […]
You all must be knowing that oxygen is necessary for the survival of human beings. However, our body has a pre-defined mechanism for transporting oxygen to body parts that require it. Transport of gases in human beings is done via a well-developed system. Many small unicellular organisms do not need a transportation system as they directly diffuse

Chemistry, Class 11, Electrochemical cells, NEET, Redox ReactionsAscorbic acid is a popular food additive since it is both a vitamin and a natural preservative. Plants require ascorbic acid as well. As the most abundant water-soluble antioxidant in plants, it not only aids in photosynthesis, cell development, and signal transduction, but it also aids in the defence against oxidative stress. Food chemists and

Chemistry, Class 11, Electrochemical cells, NEET, Redox ReactionsIntroduction: When exposed to environmental or other stresses, our bodies develop free radicals, unstable molecules that cause cell damage. Antioxidants are compounds that help prevent or reduce cell damage caused by free radicals. They are referred to as “free-radical scavengers” in some circles. Antioxidants can be obtained from various sources, both natural and artificial. It

Chemistry, Class 11, NEET, Oxidation-reduction reactions, balancing equations, Redox ReactionsFree radicals are highly reactive and unstable molecules that are produced in the body naturally as a by-product of normal metabolism, or by exposure to toxins in the environment such as tobacco smoke and ultraviolet light. Free radicals have a lifespan of only a fraction of a second, but during that time can damage DNA,

Chemistry, Class 11, NEET, Oxidation-reduction reactions, balancing equations, Redox ReactionsThis section contains a few instances of redox reactions, as well as their oxidation and reduction half-reactions. When you recharge a lead storage battery, it becomes an electrolytic cell. Electrode Processes and Redox Reactions A redox reaction is a chemical reaction in which electrons are exchanged between two reactants that are involved. Changes in the

Chemistry, Class 11, NEET, Oxidation-reduction reactions, balancing equations, Redox ReactionsMetals are found in ores generally in the form of combination with other types of elements or metals. Thus, as a result, once the metal ore has been extracted from the ground, they need to be converted into its pure metal form. This process of extracting metals from their ore is known as metal extraction.

Chemistry, Class 11, NEET, Oxidation-reduction reactions, balancing equations, Redox ReactionsIron III oxide is one of the most common oxides that you have studied in the previous classes, and it is also one of the most toxic. More in-depth information about this oxide will become available as your class progresses through the ranks. Iron III oxide has the chemical formula Fe2O3. Hematite is a mineral
Redox is a combination of the reduction and oxidation reaction. Redox reactions are chemical reactions in which electrons are transferred from one material to another. Both oxidation and reduction occur simultaneously in these processes. Changes in the oxidation states of the reacting species can be used to identify this electron transfer. Redox Reactions Types There

Chemistry, Class 11, NEET, Oxidation-reduction reactions, balancing equations, Redox ReactionsRedox processes include the reduction of one species and the oxidation of another. As a result, the oxidation state of the species in question must shift. These reactions are crucial for a variety of applications, including energy storage devices (batteries), photographic processing, and energy production and use in living systems, such as humans. Reduction is
