Corrosion rate shall increase. More Zinc will be needed to balance extra equation Fe3+ + electron = Fe2+
Corrosion rate shall increase.
More Zinc will be needed to balance extra equation
Fe3+ + electron = Fe2+
See lessCorrect answer is option B. Fe+3 ions increases the rate of reduction overall. Hence to balance ired , ioxi has to be increased. Hence. oxidation/corrosion of Zn will increase.
Correct answer is option B.
