Oxidation Vs. Reduction

Front

What is oxidation?

Back

Oxidation is the process in which a substance loses electrons.

Front

What is reduction?

Back

Reduction is the process in which a substance gains electrons.

Front

In a redox reaction, what happens to the species that is oxidized?

Back

The species that is oxidized loses electrons.

Front

What is an oxidizing agent?

Back

An oxidizing agent is a substance that gains electrons and is reduced in a chemical reaction.

Front

What is a reducing agent?

Back

A reducing agent is a substance that loses electrons and is oxidized in a chemical reaction.

Front

What does it mean when a substance is reduced?

Back

When a substance is reduced, its oxidation state decreases, meaning it gains electrons.

Front

What is the relationship between oxidation and reduction in a redox reaction?

Back

Oxidation and reduction occur simultaneously; when one substance is oxidized, another is reduced.

Front

What is a half-reaction?

Back

A half-reaction is an equation that shows either the oxidation or reduction process separately.

Front

What does the term 'electron transfer' refer to in redox reactions?

Back

Electron transfer refers to the movement of electrons from one substance to another during oxidation and reduction.

Front

How can you identify a reduction half-reaction?

Back

A reduction half-reaction shows a gain of electrons, such as Pb4+ + 2e- → Pb2+.
