Consider a Concentration Cell Comprised of Two Separate Nickel Electrodes

question 68

Multiple Choice

Consider a concentration cell comprised of two separate nickel electrodes dipped into two stable aqueous Ni⁺² salt solutions that differ in concentration. Which statement below is true regarding this concentration cell?

• A) Electricity flows in the direction from the highest concentration compartment into the lowest concentration compartment until both concentrations are identical.
• B) Electricity flows in the direction from the highest concentration compartment into the lowest concentration compartment until the lowest concentration is depleted.
• C) Electricity flows in the direction from the lowest concentration compartment into the highest concentration compartment until both concentrations are identical.
• D) Electricity flows in the direction from the lowest concentration compartment into the highest concentration compartment until the lowest concentration is depleted.
• E) Electricity will not flow in a concentration cell when both electrodes are made out of the same material (Ni dipped in Ni²⁺ aqueous solution).
