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.
Best Answer: A reducing agent is something that gains electrons and causes another atom to give up its electron in a process called oxidation. To find out which metal is the best reducing agent, you have to check the reduction potential table, which can be find online. http://www.jesuitnola.org/upload/clark/R... To answer your question, Co is the best reducing agent with a high reduction potential of 1.82 V. Source(s): I'm a biochem.
