Redox reactions - Khan Academy
But in some redox reactions, one substance can be both oxidized and reduced in the same reaction. And those are called disproportionation reactions. And here we have one the most famous examples, the decomposition of hydrogen peroxide.

When balancing equations for redox reactions occurring in basic solution, it is often necessary to add OH⁻ ions or the OH⁻/H₂O pair to fully balance the equation. In this video, we'll walk through this process for the reaction between ClO⁻ and Cr(OH)₄⁻ in basic solution.
Worked example: Balancing a redox equation in acidic solution
When balancing equations for redox reactions occurring in acidic solution, it is often necessary to add H⁺ ions or the H⁺/H₂O pair to fully balance the equation. In this video, we'll walk through this process for the reaction between dichromate (Cr₂O₇²⁻) and chloride (Cl⁻) ions in acidic solution.

For example, if copper two plus is reduced by two electrons to form solid copper, the voltage for this half reaction, or the Standard Reduction Potential, is equal to positive 0.34 volts. And for the reduction of zinc two plus ions by two electrons to form solid zinc, the Standard Reduction Potential is equal to negative 0.76 volts.
