Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals.The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.. An example of a reduction is when iron reacts with oxygen, forming iron oxides such as those called rust.

In chemistry, a suspension is a mixture of two or more components. In a suspension, very small pieces of solid are mixed in a liquid but do not dissolve. If left still, the solid pieces will separate from the liquid and either fall to the bottom or rise to the top.
