What is the reduction potential of the half-reaction 2H⁺ + 2e⁻ → H₂?

What is the reduction potential of the half-reaction 2H⁺ + 2e⁻ → H₂?

Step 1: Understand what a half-reaction is. A half-reaction shows either the reduction or oxidation process of a chemical species.
Step 2: Identify the half-reaction given: 2H⁺ + 2e⁻ → H₂. This shows that hydrogen ions (H⁺) are gaining electrons (e⁻) to form hydrogen gas (H₂).
Step 3: Know that the standard reduction potential is a measure of how likely a species is to gain electrons. It is measured in volts (V).
Step 4: Look up the standard reduction potential for the half-reaction 2H⁺ + 2e⁻ → H₂ in a standard table of reduction potentials.
Step 5: Find that the standard reduction potential for this half-reaction is 0.00 V, which is a reference point for measuring other half-reactions.
