Oxidation Number - Step-by-Step
Solve for an unknown oxidation state using the oxidation-number rules and a clear algebra setup.
Charge formats supported: Cr2O7^2-, Cr2O7 2-, Cr2O7-, NH4+, [Cr2O7]2-. Hydrates like CuSO4·5H2O are not in Phase 1.
Auto-detect picks the only “non-fixed” element (e.g., Mn in KMnO4, Cr in Cr2O7^2−).
Oxidation Number — Rule Explanation Engine
An oxidation number is the hypothetical charge an atom would carry if all its bonds to different elements were 100% ionic.
For covalent bonds, the pair of shared electrons go to the more electronegativity atom.
