How would connecting iron with a wire to a piece of metal like copper,which undergoes reduction very easily,affect the rate at which the iron corrodes?
A)It would increase the rate of corrosion.
B)It would decrease the rate of corrosion.
C)The rate would stay the same.
D)Rates are only affected by temperature.
E)none of the above

Quizplus · Accepted Answer

When iron is connected to a more easily reducible metal like copper, it acts as the anode while the copper acts as the cathode. This creates a potential difference between the two metals and results in an increased flow of electrons from the iron to the copper. This causes accelerated corrosion of the iron, as more electrons are available for the oxidation reaction. Thus, connecting iron with a wire to a piece of copper would increase the rate of corrosion of the iron.
