WebThis is a basic exercise in assigning oxidation numbers to simple compounds and ions. When you press "New Problem", a compound will be displayed and you will be asked to assign an oxidation number to one of the atoms present. Enter the value in the cell and press "Check Answer". If the oxidation number is positive or 0, juste enter the value. WebOxidation–reduction or redox reactions are reactions that involve the transfer of electrons between chemical species (check out this article on redox reactions if you want a refresher!). The equations for oxidation-reduction reactions must be balanced for both mass and charge, which can make them challenging to balance by inspection alone.
