Question

An electrochemical cell is constructed such that on one side a pure nickel electrode is in contact with a solution containing Ni2+ions at a concentration of 3 x 10-3 M. The other cell half consists of a pure Fe electrode that is immersed in a solution of Fe2+ ions having a concentration of 0.1 M. At what temperature will the potential between the two electrodes be + 0.140 V?

Answer 1

Answer:

Explanation:

This problem asks for us to calculate the temperature for a nickel-iron electrochemical cell when the potential between the Ni and Fe electrodes is +0.140 V. An electrochemical cell is constructed such that on one side a pure nickel (Ni) electrode is incontact with a solution containing Ni2+ ions at a concentration of 3 × 10-3M. The other cell halfconsists of a pure iron (Fe) electrode that is immersed
