What does the reduction potential chart tell about two elements?
Type your answer here... Which is more likely to be reduced
When finding the emf of a redox reaction by Ered cathode - Ered anode and a half-reaction is reversed on the chart do you flip the sign of its reduction potential?
No, because the chart shows reduction potentials. Ered cathode - Ered anode = emf just requires you to plug in the reduction potentials the way they are. A common equation is Ered cathode + Eox anode = emf, in which case you would have to flip the sign of the anode's reduction potential, since you would need its oxidation potential. But the equation Ered cathode - Ered anode = emf is simpler and probably formed to be that way.
What does the reduction potential chart tell you about two elemnts?
The reduction potential chart provides information on the ability of an element to gain electrons. Elements with higher reduction potentials have a greater ability to gain electrons and are more likely to be reduced, while elements with lower reduction potentials are less likely to gain electrons and are more likely to be oxidized. Comparing the reduction potentials of two elements can indicate which one is more likely to be reduced in a chemical reaction.
How is an oxidation half-reaction written using the reduction potential chart?
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
What is the relative standard reduction potential of the half-cell in which reduction occurs?
The relative standard reduction potential of a half-cell is a measure of the tendency of a species to gain electrons and undergo reduction. It is defined relative to a standard hydrogen electrode, which is assigned a potential of 0 V. The more positive the reduction potential, the greater the tendency for reduction to occur in that half-cell.
How is an oxidation half reaction written using the reduction potential chart?
To write an oxidation half reaction using the reduction potential chart, simply reverse the reduction half reaction from the chart. This means changing the sign of the reduction potential value and flipping the direction of the reaction arrow. Remember to balance the reaction by adding any necessary electrons.

What does a reduction potential chart show?
How likely chemical species are to gain electrons and therefore, be "reduced". Reduction potential is measured in volts(V) and the more positive the reduction potential value, the more likely it will be reduced.

Elements with higher reduction potentials have a greater ability to gain electrons and are more likely to be reduced, while elements with lower reduction potentials are less likely to gain electrons and are more likely to be oxidized. Comparing the reduction potentials of two elements can indicate which one is more likely to be reduced in a chemical reaction.
What pair of half-reacations would have a negative total reduction potential?
A pair of half-reactions with reduction potentials that differ in sign will result in a negative total reduction potential. For example, a half-reaction with a reduction potential of +0.8 V paired with a half-reaction with a reduction potential of -0.7 V would give a negative total reduction potential (+0.8 V - (-0.7 V) = +1.5 V).
How is an oxidation half-reaction written using the reduction potential chart?
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
Which element has the highest standard reduction potential?
The element with the highest standard reduction potential is fluorine.
Is a half-cell's standard reduction potential positive?
Yes, a half-cell's standard reduction potential is positive if the reduction reaction is spontaneous under standard conditions.
What is the relative standard reduction potential of the half-cell in which reduction occurs?
The relative standard reduction potential of a half-cell is a measure of the tendency of a species to gain electrons and undergo reduction. It is defined relative to a standard hydrogen electrode, which is assigned a potential of 0 V. The more positive the reduction potential, the greater the tendency for reduction to occur in that half-cell.
What is the total reduction potential of a cell i which potassium is reduced and copper is oxidized?
The total reduction potential of a cell can be calculated by subtracting the standard reduction potential of the oxidation half-reaction from that of the reduction half-reaction. For potassium (K) being reduced, the standard reduction potential is approximately -2.93 V, while for copper (Cu) being oxidized, its reduction potential is +0.34 V. Thus, the total reduction potential of the cell is calculated as: E_cell = E_reduction (Cu) - E_reduction (K) = 0.34 V - (-2.93 V) = 3.27 V. This positive value indicates that the cell reaction is spontaneous.
