What is a reducing agent?
Reducing agent can be defined as those groups which gain oxygen atom from the substrate (or oxidizing agent) although it is not true in every case as in many redox reactions, oxidation – reduction takes place in absence of oxygen atoms. Examples of these reducing agents include formic acid, oxalic acid, sulfites etc.
What are some examples of oxidizing agents?
Oxygen, hydrogen peroxide and halogens are examples of some common oxidizing agents. The oxidizing agent can be defined as those groups which transfer oxygen atom to the substrate although its not true in every case as in many redox reactions, oxidation – reduction takes place in absence of oxygen atoms as well.
What is a redox reaction?
What are Redox Reactions? The term redox is made up of two words reduction and oxidation. A type of chemical reaction that involves a transfer of electrons between two species is called redo x reaction. In these types of reactions oxidation and reduction both take place together.
What is disproportionation reaction?
Disproportionation Reactions – These are special type of redox reactions. In these reactions an element in one oxidation state is simultaneously oxidized and reduced. In these reactions one of the reacting substances always contains an element that can exist in at least three oxidation states.
What method is used to balance redox reactions?
Balancing of Redox Reactions - For balancing the redox reactions oxidation number method and half reaction method are used.
How does glucose turn into carbon dioxide?

(image will be uploaded soon) Combustion – Combustion is an exothermic redox chemical reaction which occurs at high temperature and in presence of an oxidant.
What is a redox reaction?
What is Redox Reaction. Many chemical reactions involve transfer of electrons from one chemical substance to another. These electron transfer reactions are termed as oxidation-reduction or Redox reaction, or those reactions which involve oxidation and reduction both simultaneously are known as oxidation and reduction/ Redox reaction.

How to find oxidation number?
How do we calculate oxidation number? Well, for calculating oxidation number, one has to consider various oxidation states of all atoms in a molecule and then equate the sum of all of them to the net charge on the molecule. There are various rules for finding oxidation number of an atom in a molecule however, here we will just see how to find oxidation number of Cl in HClO 3.
What is redox in chemistry?
The word ‘redox’ is the acronym for reduction-oxidation that occurs in a certain chemical reaction. Put more simply, these reactions are those sets of chemical equations in which the oxidation number of the atoms involved in the chemical reaction changes when the reaction occurs. This definition introduces us to another fundamental concept in chemistry that is of crucial importance, the oxidation number. Let us define it.
What are the changes that occur during oxidation?
So on a general note, oxidation generally involves any of the following changes: Loss of electrons. Loss of hydrogen atoms. Gain of oxygen. Increase in oxidation state. Similarly, reduction is said to occur when any of the following changes occur: Gain of electrons. Gain of hydrogen atoms. Loss of oxygen atoms.
How does hydrogen oxidize?
In the first reaction, hydrogen oxidizes by increasing its oxidation number from 0 to +1 while in the second reaction, fluorine is reduced by decreasing its oxidation number from 0 to -1. Eventually, net charge on the molecules formed is zero as number of electrons gained during oxidation are consumed during reduction process.
