Why is the addition of electrons to a reactant called reduction?
| a. |
because the negative charge of the oxidizing agent is increased |
|
| b. |
because the oxidizing agent loses electrons |
|
| c. |
because the atomic mass of the oxidizing agent is reduced |
|
| d. |
because the positive charge of the oxidizing agent is reduced |
|
| e. |
because the atomic weight of the reducing agent is reduced |
Homework Answers
D.because the positive charge of the oxidizing agent is reduced.
oxidation came to be defined as removal of electrons from an atom leading to an increase in its positive charge, and reduction as addition of electrons resulting in a decrease (reduction) in positive charge.For example, in the reduction of ZnO to metallic Zn, the positive charge on the metal atom get decreased (reduced) from +2 to zero.
