Balancing REDOX reactions

Front

What is a REDOX reaction?

Back

A REDOX reaction is a chemical reaction that involves the transfer of electrons between two species, resulting in changes in oxidation states.

Front

What does oxidation mean in a REDOX reaction?

Back

Oxidation is the process in which an atom, ion, or molecule loses electrons, resulting in an increase in oxidation state.

Front

What does reduction mean in a REDOX reaction?

Back

Reduction is the process in which an atom, ion, or molecule gains electrons, resulting in a decrease in oxidation state.

Front

What is the oxidation number of an element in its elemental form?

Back

The oxidation number of an element in its elemental form is 0.

How do you determine the oxidation number of oxygen in compounds?

Back

In most compounds, oxygen has an oxidation number of -2, except in peroxides where it is -1.

Front

What is the oxidation number of hydrogen in most compounds?

Back

The oxidation number of hydrogen is +1 in most compounds, except when bonded to metals where it is -1.

Front

What is the oxidation number of chlorine in compounds?

Back

The oxidation number of chlorine is usually -1, but it can be positive in compounds with oxygen or fluorine.

Front

In a REDOX reaction, what happens to the reducing agent?

Back

The reducing agent is oxidized and loses electrons during the reaction.

Front

In a REDOX reaction, what happens to the oxidizing agent?

Back

The oxidizing agent is reduced and gains electrons during the reaction.

Front

What is the half-reaction method in balancing REDOX reactions?

Back

The half-reaction method involves separating the oxidation and reduction processes into two half-reactions and balancing them individually.
