Ice it. Ice your injury for 20 to 30 minutes every 3 to 4 hours to reduce pain and swelling. Continue this for 2 or 3 days, or until the pain is gone. Compress your leg. Use an elastic bandage around the lower leg and ankle to keep down swelling.
Finally, two terms you may run across in the future are oxidizing agent (or oxidant) and a reducing agent (reductant). An oxidizing agent causes oxidation and is reduced in the reaction. A reducing agent causes the reduction in the redox reaction. The reducing agent is oxidized in the reaction.
Oxidation-loss of electrons/gain of oxygen. Species oxidized-the one that lost electrons or gained ozygen. Species reduced-the one that gained electrons or lost oxygen.Oxidizing agent-gets reduced.Reducing agent-gets oxidized. In your equation, Mg went from 0 oxidation number to +2, i.e lost electrons i.e. got oxidized i.e. is the reducing agent.5. Location: Los Angeles, CA. Species oxidized is the atom that is being oxidized (oxidized is losing electrons), whereas the oxidizing agent is the one that is doing the oxidizing...therefore, the oxidizing agent is being reduced.
