Two terms: Oxidation and Reduction.
Oxidation: - Any reaction with oxygen;
-Loss of Electron.
Reduction: - Any reaction that produced metal from ores;
- Gain of Electrons.
REDOX reaction: There is gaining and losing of electrons.
Oxidizing agent (OA) is defined as the one entity that will donate electrons, therefore promoting oxidation on the other entity.
Reduction agent (RA) is defined as the one entity that will receive that electron, therefore promoting the other entity.
DOUBLE REPLACEMENT, OR ACID AND BASE REACTIONS ARE REDOX
