What is an oxidation number calculator?
The oxidation number calculator also belongs to the group of chemical calculators, which is used exclusively to find the oxidation number of all the elements present in a chemical compound.
This oxidation state calculator can help you to calculate the chemical fractions faster and displays the oxidation state of any element in any chemical compound in just a few seconds.
What is the oxidation number in chemistry?
In chemistry, we assign each atom a specific number based on the number of electrons it loses or gains during the formation of the compound. Thus, the oxidation number or state keeps the record of electrons gained or lost by an atom.
As we know, the atom which gains electrons develops a negative charge and vice versa; the oxidation number could also be negative, positive, and zero as either it loses or gains electrons or stays intact.
During a chemical reaction, we analyze the oxidation state of each element and the corresponding changes in their oxidation states to track the overall electron transfer. Don't forget that the oxidation state doesn't represent the actual charge over the entire molecule. Instead, it only covers the charge over a single atom in the substance.
To calculate the number of electrons an atom accepts or donates during a reaction, you can use this oxidation number calculator rather than immersing yourself in complex rules and evaluations.
How to use an oxidation number calculator?
To use the oxidation number calculator, you only have to follow a few basic steps as follows
- Write the chemical formula of the compound accurately. While writing the chemical formula, pay special attention to capital and small letters. If you write CAOH2 rather than CaOH, the calculator will not detect the substance.
- Write the correct number of atoms of each element present in the compound. Remember, if you skip or mistakenly add more atoms of an element, the entire nature of your substance will change. Eventually, the oxidation number of each reacting element will be altered. To confirm the correct number of atoms in the compound, you can use our equation balancer.
- Avoid using unnecessary brackets  or parenthesis () while writing chemical formulas.
- After inserting the formula, click on the balance or calculate button and wait a few seconds.
The result of your query regarding the oxidation number or state of all the elements in a compound will be shown in four major sections as follows
- Input interpretation that will state the general or chemical name of your substance.
- The overall result comprises the complete lewis diagram showing bonding between every element and a thorough representation of electron transfer.
- Chemical names and formulas that will embody the hill formula, chemical formula, and general name of the substance.
- Ion equivalent section that will show the number of anions and cations in the complete compound.
How does the oxidation number calculator work?
Our oxidation number calculator is based on the Lewis diagram method to calculate an element's oxidation number in a compound. For this purpose, the steps taken by the tool to derive final results are as follows
- Firstly, the calculator draws the complete Lewis diagram showing interacting atoms and their valence electrons.
- Secondly, it is estimated which atom is gaining or donating the electron in the compound. It is done by keeping the general rule in front; electrons draw towards more electronegative atoms and bond pairs. On the other hand, the electrons are divided equally among homonuclear bonds.
- Based on this bonding and the total count of atoms of each element, the final result is concluded.
Why should you use our oxidation number calculator?
- As mentioned before, finding the oxidation number of an atom, especially when it is a part of a chemical compound, is quite a tricky thing. You have to pay attention to bonding attributes, ionic approximations, and atomic count to avoid making mistakes.
- Mostly the online oxidation number calculator present on the web offer to count the oxidation state of atoms in the free state. If any of those allow you to calculate oxidation numbers in complexes, you will be subjected to some digits as a result.
On the other hand, this chemical calculator saves you from all this annoyance, and you can find the oxidation number in the simplest to most complex compounds in a few instants.
On the other hand, this calculator shows a complete stepwise method of deriving the oxidation state. You will go through all the bonding parameters and atomic interactions to understand how oxidation numbers of each atom in a complex get changed after the reaction.
