  • Writing Ionic Equations for Redox Reactions
    Writing ionic equations for redox reactions You can split the ionic equation into two parts, and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons, and the copper(II) ions have gained them.
