An oxidation number calculator helps determine the oxidation state of elements in chemical compounds. Oxidation numbers indicate the gain or loss of electrons during a chemical reaction and are essential for understanding redox reactions, balancing equations, and analyzing chemical compounds.
How to Use the Oxidation Number Calculator
Step 1: Enter the Chemical Formula
Input the formula of the compound (e.g., H₂O, NaCl, KMnO₄).
Step 2: Specify Known Oxidation Numbers (If Needed)
The calculator assumes standard oxidation numbers but allows you to provide custom inputs for certain elements.
Step 3: Calculate
The tool automatically computes the oxidation numbers for each element in the compound following oxidation state rules.
Example Calculation
For H₂O (water):
- Hydrogen has an oxidation number of +1.
- Oxygen has an oxidation number of -2.
Rules for Determining Oxidation Numbers
- Elemental Form: Oxidation number is always 0 (e.g., O₂, N₂).
- Monoatomic Ions: Equal to the ion charge (e.g., Na⁺ = +1, Cl⁻ = -1).
- Compounds: The sum of oxidation numbers equals the compound's total charge.
- Hydrogen: Usually +1 (except in metal hydrides).
- Oxygen: Typically -2 (except in peroxides).
