Question

Give an example of a redox reaction. Indicate the substance that is oxidized and that is reduced.

Answer 1

Part 1: Redox reaction:

• Redox reactions are reactions in which both the oxidation and reduction processes take place simultaneously.

Part 2: Example of redox reaction:

• An example of a redox reaction is:
• $\underset{\mathrm{Lead}\mathrm{oxide}}{\mathrm{PbO}\left(\mathrm{s}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Lead}}{\mathrm{Pb}\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
• In the above reaction, hydrogen is oxidized to water and lead oxide is reduced to lead.
