Question | Answer |
Explain why metals tend to be oxidized and nonmetals tend to be reduced. | Metals have low ionization energies and low electron affinities so they are readily oxidized Nonmetals have high ionization energies and high electron affinities so they are readily reduced. |
Why is the oxidized substance also called the reducing agent? | It takes oxygen from the oxidizing agent in the oxidation/reduction reaction |
In each of the following, determine which reactant is being oxidized and which is being reduced. Al(s) + O2(g) ® Al2O3(s) Ca(s) + F2(g) ® CaF2(s) | Al goes from oxidation number 0 to +3 and it is oxidized O goes from 0 to - 2 and it is reduced Ca goes from 0 to +2 and it is oxidized F goes from 0 to -2 and it is reduced |
