What additions must you make to the cell for it to generate a standard emf?
Check all that apply.
- We should add enough salt containing B2+ into the glass containing the electrode B(s) to produce a 1 M B2+ solution.
- We should apply the initial emf to the electrodes.
- We should add enough salt containing A2+ into the glass containing the electrode A(s) to produce a 1 M A2+ solution..
- We should add enough salt containing A2+ into the glass containing the electrode B(s) to produce a 1 M A2+ solution..
- We should add enough salt containing B2+ into the glass containing the electrode A(s) to produce a 1 M B2+ solution.
- We should add the salt brige.
The cell’s potential (electromotive force, also known as emf) for an electrochemical device is the potential that is measured for the redox reaction process that is operating under the standard state. This includes an average cell temperature of 25,0 degrees Celsius and every redox-active aqueous substance with a molarity value that is 1.0 to 1.0. These aqueous substances are typically paired with a solid electrodes in the oxidation/reduction reactions that occur in an cathode and anode half-cell. If any of the of the molarity values change in the cell, the potential is altered from its normal value. The shift is triggered by the reaction quotient that is included in the Nernst equation. The term is created from the selected non-standard molarity value along with the balanced coefficients for their species.
