Redox Reactions and Concepts of Oxidation and Reduction

Vocabulary flashcards covering the classical and modern definitions of oxidation and reduction, as well as specific half-reaction examples from the text.

Redox Reaction

A reaction in which oxidation and reduction take place simultaneously, involving the gain or loss of electrons.

Oxidation (Classic Concept)

A chemical process that involves the addition of oxygen, the removal of hydrogen, or both.

Reduction (Classic Concept)

A chemical process that involves the addition of hydrogen, the removal of oxygen, or both.

Oxidation (Modern Concept)

A process that involves the removal of electrons or an increase in the oxidation state of one or more elements.

Reduction (Modern Concept)

A process that involves the addition of electrons or a decrease in the oxidation state of one or more elements.

Oxidation Example ($Fe$ to $FeO$)

A classical oxidation reaction represented by $Fe \rightarrow FeO$, showing the addition of oxygen.

Oxidation Example ($CH_3CH_2OH$ to $CH_3COOH$)

A classical oxidation reaction represented by $CH_3CH_2OH \rightarrow CH_3COOH$.

Reduction Example ($ZnO$ to $Zn$)

A classical reduction reaction represented by $ZnO \rightarrow Zn$, showing the removal of oxygen.

Reduction Example ($C_2H_4$ to $C_2H_6$)

A classical reduction reaction represented by $C_2H_4 \rightarrow C_2H_6$, showing the addition of hydrogen.

Reduction Example ($CH_3COOH$ to $CH_3CH_2OH$)

A classical reduction reaction represented by $CH_3COOH \rightarrow CH_3CH_2OH$.

Oxidation Half-Reaction Example ($Zn$)

Oxidation Half-Reaction Example ($Cl^-$)

A modern oxidation reaction represented by $2Cl^- \rightarrow Cl_2 + 2e^-$.

Reduction Half-Reaction Example ($Cu^{2+}$)

A modern reduction reaction represented by $Cu^{2+} + 2e^- \rightarrow Cu$.

Reduction Half-Reaction Example ($MnO_4^-$)

A modern reduction reaction represented by $MnO_4^- + 8H^+ + 5e^- \rightarrow Mn^{2+} + 4H_2O$.

Oxidation Half-Reaction Example ($Cl_2$)
