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.

Which element has the highest standard reduction potential?

The element with the highest standard reduction potential is fluorine.


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.

How are standard electrode potentials listed in the Standard Reduction Potentials table?

Standard electrode potentials are listed in the table in decreasing order, with the strongest reducing agents (highest standard reduction potentials) at the top and the strongest oxidizing agents (lowest standard reduction potentials) at the bottom. The potentials are measured relative to the standard hydrogen electrode.


A voltaic cell is made of copper and aluminum electrodes What is the emf of this cell?

The EMF of a copper-aluminum voltaic cell can be determined by the standard reduction potential of each metal. Copper has a higher standard reduction potential than aluminum, so the cell will have a positive EMF. The exact value can be determined by calculating the difference between the reduction potentials of copper and aluminum.

What is the voltage of a galvanic cell made with silver(ag) and nickel(ni)?

The voltage of a galvanic cell made with silver (Ag) and nickel (Ni) can be calculated using their standard reduction potentials. Silver has a standard reduction potential of +0.80 V, while nickel has a standard reduction potential of -0.25 V. The overall cell potential can be determined by subtracting the reduction potential of nickel from that of silver, resulting in a voltage of approximately +1.05 V for the cell.


What is the standard cell potential for a cell made from gold and copper?

The standard cell potential for a cell made from gold and copper is the difference in standard reduction potentials between the two metals. The standard reduction potential for gold is +1.50 V and for copper is +0.34 V. Therefore, the standard cell potential would be 1.50 V - 0.34 V = 1.16 V.
