      In your chemistry data booklet, there is a large redox table. Where on the table do you find the strongest oxidizing agent and the strongest reducing agent. (2) Write the spontaneity rule that you could use for determining if a reaction is spontaneous or non-spontaneous based of the half reactions from the redox reactions on your data sheet.

      : Forcing a non-spontaneous redox reaction to occur by applying an external voltage that opposes the spontaneous flow of electrons. Electrolysis of water (demonstration) At room temperature, the following reaction is spontaneous (remember the Hindenburg!) and has a large equilibrium constant. 2 H2 (g) + O2 (g) → 2 H2O (l)

    • Redox - Wikipedia

      A battery is a redox reaction. Redox is the transfer of electrons while acid/base chemistry involved the transfer of protons. Precipitation, unlike these two types of reactions, does not involve a transfer as such but the combination of existing ions in solution such that an insoluble compound is formed.

      The breathalyzer reaction uses a spontaneous redox reaction between acidic Cr2O72- and ethanol C2H5OH. If alcohol is present in your breath sample, it will react with a solution of Cr2O72- reducing the orange color as it reacts to form Cr3+, which is green.

      The reaction between hydrogen peroxide and yeast is similar to the breakdown of hydrogen peroxide that can occur in the cells of your body. Yeast is a catalyst that allows the reaction to take place. When yeast and hydrogen peroxide are mixed together, hydrogen peroxide, H2O2, is broken down into water, H2O, and oxygen gas, O2, as shown below.

      A redox reaction is the simultaneous occurrence of the two components or half reactions. Oxidation occurs when a chemical species loses or gives up electrons to another chemical species. Reduction occurs when a chemical species receives or gain electrons. The oxidation process provides the electrons necessary for reduction to occur.

      Oxidation – Reduction Packet Oxidation-reduction (redox) reactions are reactions in which oxidation numbers change. Oxidation numbers are either real charges or formal charges which help chemists keep track of electron transfer. In practice, oxidation numbers are best viewed as a bookkeeping device.
