Redox Reactions

Front

What are redox reactions?

Back

Redox reactions are chemical reactions that involve the transfer of electrons between two species, resulting in changes in oxidation states.

What is oxidation?

Back

Oxidation is defined as the loss of electrons by a substance during a chemical reaction.

Front

What is reduction?

Back

Reduction is defined as the gain of electrons by a substance during a chemical reaction.

Front

What is an oxidizing agent?

Back

An oxidizing agent is a substance that oxidizes another substance by accepting its electrons.

Front

What is a reducing agent?

Back

A reducing agent is a substance that reduces another substance by donating its electrons.

Front

What is a half-reaction?

Back

A half-reaction is an equation that shows either the oxidation or reduction process separately, indicating the transfer of electrons.
