What is REDOX?

Back

REDOX (reduction-oxidation) refers to a type of chemical reaction that involves the transfer of electrons between two species. It encompasses both reduction (gain of electrons) and oxidation (loss of electrons).

What is oxidation in a REDOX reaction?

Back

Oxidation is the process in a REDOX reaction where a substance loses electrons, resulting in an increase in oxidation state.

Front

What is reduction in a REDOX reaction?

Back

Reduction is the process in a REDOX reaction where a substance gains electrons, leading to a decrease in oxidation state.

Front

What is an oxidizing agent?

Back

An oxidizing agent is a substance that facilitates oxidation by accepting electrons from another substance, thereby causing that substance to be oxidized.

Front

What is a reducing agent?

Back

A reducing agent is a substance that donates electrons to another substance, causing that substance to be reduced.

Front

How do you identify oxidation and reduction in a reaction?

Back

To identify oxidation and reduction, look for changes in oxidation states of the elements involved. An increase in oxidation state indicates oxidation, while a decrease indicates reduction.

Front

What is the role of electrons in REDOX reactions?

Back

Electrons are transferred between reactants in REDOX reactions, with one species losing electrons (oxidation) and another gaining them (reduction).

Front

What is the significance of REDOX reactions in biological systems?

Back

REDOX reactions are crucial in biological systems for processes such as cellular respiration and photosynthesis, where energy transfer occurs.

Front

Can REDOX reactions occur without a solvent?

Back

Yes, REDOX reactions can occur in gas or solid phases, not just in solutions.

Front

What is the relationship between REDOX reactions and energy?

Back

REDOX reactions often involve energy changes; the transfer of electrons can release or absorb energy, which is harnessed in various chemical processes.
