Redox Reactions Assignment Help

Redox Reactions are everywhere around us. We use these kinds of reactions in our day to day lives one of the best examples of such a reaction is the conversion of oxygen to carbon dioxide by our body in the process of breathing. Or the way a battery uses the chemicals inside it to produce electrical power is also based upon the working of a redox reaction. To understand this, one of the first thing, that is very elemental to this article that we need to know is that what is a redox reaction? We can define a redox reaction as a reaction in which, to form the output substrate, there needs to be an exchange of electrons from the input substance to the output one. One of the confusion the students have while studying the redox reactions is that the redox reaction will definitely bring a change in the number of electrons. This is not true because this kind of reaction will only bring a change in the number of electrons when there is a difference in the oxidation number of the two products reacting. Some of the common questions that come in the Mind of the student as soon as they look at a reaction, what is the oxidation agent in this reaction, what is the reduction agent in this reaction and also how to identify if a reaction is a redox reaction or not. If you are one of the students who is facing such problems in the field of chemistry, to be precise electrochemistry then this article is just for you because in this we aregoing to discuss some of the very basic concepts related to redox reactions. As the name suggests reducing agent, this means that this compound or an element will be losing or be getting reduced, hence we can deduce that the reducing agent in the redox reaction is a compound that loses a certain number of electrons when the reaction happens. When a compound loses its electrons in a reaction, such a compound is known as to be oxidised by the other compound under reaction. Similarly, we can define an oxidising agent in a redox reaction to be a compound that gains an electron when a reaction takes place. Since the compound that loses an electron is said to be oxidised similarly when a compound gains an electron in a redox reaction, it is said to be reduced.

Just like every other kind of reaction in chemistry, redox reaction can be divided into a certain number of types based on the type of reaction is happening. a redox reaction can be divided into three major types. They are explained below as follows:

  1. Combustion reactions: When a compound reacts with molecule are oxygen to form oxygen-containing compounds, such a reaction is known as the combustion reaction. This reaction usually tends to produce a lot of energy along with a lot of carbon dioxide and water once the reaction is finished.
  2. Disproportionation reactions: The type of reaction in which the only one of the compound is oxidised and then reduced is known as a disproportionate reaction.
  3. Single replacement reactions: This type of reaction is also known as switching reaction because, in this, compounds that are being oxidised and reduced switch after the reaction is complete and hence comes the name single replacement reaction.

By this time, most of you reading this article must have understood the basic meaning and some features of a redox reaction but still you are confused about how to find the balancing states of a particular molecule or an atom when it undergoes a reaction. Down below we have segregated the process for the same into very simple steps and they go as follows:

  1. For each type of atom present in the reaction, the oxidation state of each one of them is calculated and written down somewhere aside.
  2. All the half reactions that are being done in the reaction are to be written.
  3. The number of electrons present on each side of the reaction equation needs to be equalised or made a multiple of each other so that they cancel out each other and we have nothing to spare.
  4. Bring both sides of the equation to a single one and then they are added so that they become a single equation and can be simplified easily.

With the help of reading this article, we can assume that you have a good and well-settled explanation of what redox reactions actually mean, why they are called so, what are the particular things that happen when a redox reaction takes place and also the steps that are needed to make a balanced redox reaction.
