What is the standard reduction potential for the half cell?

NO3−​(aq.) +2H+(aq.) +e−→NO2​(g)+H2​O is 0.

What does the standard reduction potential indicate about a half-reaction?

What does the standard reduction potential indicate about half-reaction? The larger the standard reduction potential, the more likely the half-reaction will occur as a reduction. If the standard reduction potential of a a half-cell is positive, which redox reaction is spontaneous when paired with a hydrogen electrode?

What are half cell potentials?

The half-cell potential test is the only corrosion monitoring technique standardized in ASTM C876 – 15: Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures.

What is the reduction potential of Cu in aqueous solution?

The standard reduction potential for Cu2+/Cu is 0.34 V.

How are electrode potentials listed in a reduction?

All tabulated values of standard electrode potentials by convention are listed for a reaction written as a reduction, not as an oxidation, to be able to compare standard potentials for different substances ( Table P1 ).

What are the reduction potentials for sulfuric acid?

The standard reduction potentials are Pb2++ 2e– Pb E° = –0.13 V Cu2++ 2e– Cu E° = +0.34 V If sulfuric acid is added to the Pb(NO 3 2 solution, forming a precipitate of PbSO

Which is the difference between the tabulated reduction potentials?

The standard cell potential (E° cell) is therefore the difference between the tabulated reduction potentials of the two half-reactions, not their sum: E°cell = E°cathode− E°anode

What is the reduction potential for Zn2 + 2AG?

6. The standard potential for the reaction Zn + 2Ag+ Zn2++ 2Ag is 1.56 V. Given that the standard reduction potential for Ag++ e– Ag is 0.80 V, determine the standard reduction potential for Zn2++ 2e– Zn. A) -0.76 V B) 0.04 V C) 0.76 V D) -0.38 V E) none of these
