Warm-Up: Oxidation Reduction (Redox)

Front

What is oxidation?

Back

Oxidation is the process of gaining oxygen or losing electrons in a chemical reaction.

Front

What is reduction?

Back

Reduction is the process of gaining electrons or losing oxygen in a chemical reaction.

Front

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

Back

The species that is reduced gains electrons and is the oxidizing agent.

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 the oxidation state of an element?

Back

The oxidation state (or oxidation number) is a measure of the degree of oxidation of an atom in a compound.

Front

What occurs during oxidation in terms of electrons?

Back

During oxidation, an atom or molecule loses electrons.

Front

What occurs during reduction in terms of electrons?

Back

During reduction, an atom or molecule gains electrons.

Front

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

Back

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

Front

What is the significance of redox reactions in biological systems?

Back

Redox reactions are crucial for processes like cellular respiration and photosynthesis.
