Oxidation or reduction processes in redox reactions
How electrons are transferred
Loss of electrons
Gain of electrons
Na→Na++e−\text{Na} \rightarrow \text{Na}^+ + e^-Na→Na++e−
Cl2+2e−→2Cl−\text{Cl}_2 + 2e^- \rightarrow 2\text{Cl}^-Cl2+2e−→2Cl−
Electrons lost must equal electrons gained
Only species directly involved in the reaction
Ions that do not change during the reaction
They are omitted
Write the balanced chemical equation
Na+\text{Na}^+Na+ and NO3−\text{NO}_3^-NO3−
