Introduction to Oxidation Number Calculator

The oxidation state calculator is here to make the process of determining oxidation numbers easy. This online tool automatically finds the oxidation number making it easier for everyone.

Oxidation Number Calculator

Now you don’t need to manually calculate, rather our oxidation number method calculator will help you. By putting the chemical formula or element our oxidation calculator provides you with the oxidation number for each element or compound.

What are Oxidation Numbers?

A number that is assigned to each compound is called an oxidation number. When an element loses or gains an electron its oxidation number decreases or increases. It can be positive, negative, or zero depending upon the loss or gain of electrons by an element.

It also describes how many electrons are lost by each element. For example, the oxidation number of Carbon ( C ) is -1 in benzene and +4 in CO2. So, it depends on the number of electrons gained or lost by an element.

Similar to this, use our half life formula calculator to know the Half life of Carbon.

How to Calculate Oxidation State?

You can calculate oxidation numbers using an oxidation number calculator but you also have to do it manually. Here are some examples to calculate oxidation state manually,

Examples for Finding Oxidation Numbers

Example 1: Find out the Oxidation number of Carbon in CO2:

CO2 is neutral, so net charge = 0

$$ Oxidation \; state \; of \; CO_2 \;=\; Oxidation \; state \; of \; C \;+ Oxidation \; state \; of \; O $$ $$ Oxidation \; state \; of \; CO_2 \;=\; 0 $$ $$ Oxidation \; state \; of \; O \;=\; (-2)2 $$ $$ Oxidation \; state \; of \; O \;=\; -4 $$ $$ Oxidation \; states → -4 + x \;=\; 0 $$ $$ Oxidation \; states → x \;=\; +4 $$

Atoms in the species → CO2

$$ Oxidation \; state \; of \; CO_2 \;=\; +4 $$

Example 2: Find the oxidation number of Hydrogen in CH4:

CH4 is neutral, so net charge = 0

$$ Oxidation \; state \; of \; CH_4 \;=\; Oxidation \; state \; of \; C \;+ Oxidation \; state \; of \; H $$ $$ Oxidation \; state \; of \; CH_4 \;=\; 0 $$ $$ Oxidation \; state \; of \; C \;=\; -4 $$ $$ Oxidation \; state → -4 + x = 0 $$ $$ Oxidation \; state → x = +4 $$

Atoms in the species → CH2

$$ Oxidation \; state \; of Hydrogen in \; CH_4 \;=\; +4 $$

In CH4, the oxidation number of Hydrogen (H) in CH4 (methane) is +4. The reason is that there are four Hydrogen atoms in CH4 and each Hydrogen atom has an oxidation number of +1. To balance such reactions you may utilize our Balancer for chemical equations.

Why Oxidation numbers are Important in a Chemical Reaction?

An element has an oxidation number when it is in the form of a compound. Actually, It is the oxidation state of the element in a compound. In chemical reactions Oxidation numbers are important because they help us:

  • Knowing what compound is going to form as a result of this reaction.
  • Predicting the charge on ions in a molecule.
  • Understanding the nature of a molecule or compound has
  • Tracking the number of electrons during the chemical reaction
  • Differentiating different molecules of two elements.

Sometimes a reaction can be an oxidation reduction reaction for which you may utilize our reduction reaction calculator.

How to Find an Oxidation State Calculator?

Finding an online oxidation number tool is so easy. We will tell you how you can get a more accurate online oxidation tool.

  • First of all, open your web browser and write an online oxidation number calculator.
  • You can click our oxidation number method calculator.
  • Now familiarize yourself with the interface of the calculator.
  • You will see an input field where you have to enter your compound, for example, H2O.
  • Now, click on the calculate button to initiate the process of calculation.

Way of Finding Oxidation Numbers

The oxidation number of an element varies according to its bond with other elements. If an element is alone and there’s no other element attached to it then this element is said to be neutral which you can find by using solver for elemental analysis.

If you want to know the oxidation number of atoms in a molecule then first of all separate the atom from its molecule or its bonding partner. If the compound is binary ionic then the oxidation number of each element is equal to the charge on that element.

Benefits of Our Oxidation Number Calculator:

Using our oxidation state calculator is so beneficial. In today’s world, everyone wants speedy results. So, Our oxidation calculator is here to perform the task faster to save your time and effort.

It doesn’t only save time and effort but also gives you accurate results which is helpful for you. It decreases the chances of errors in oxidation numbers expected by humans. Our oxidation number calculator is user-friendly and understandable for a beginner and an expert.

Our oxidation state calculator can be used at any time as long as our user has his device and internet which in today’s world everyone has access to. This makes it easier for students, professionals, and anyone else who has an interest in chemistry or finding oxidation numbers.

Related: You may use our percentage composition calculator for finding the percentage of elements in a molecule or compound.

Conclusion

To conclude, finding the oxidation numbers of compounds is important during a chemical reaction. Our oxidation number calculator with steps is a valuable tool for you if you want to know the oxidation number of a compound. It simplifies each step and gives you a precise answer. So you don't need to worry about finding the oxidation numbers. Our oxidation calculator is always here for you.
