Question: A 1.00 M solution of KI was electrolyzed using inert electrodes. Assume that all oxidations and reductions occur at their standard potentials (no overvoltage). A.

A 1.00 M solution of KI was electrolyzed using inert electrodes. Assume that all oxidations and reductions occur at their standard potentials (no overvoltage).

A. Write the oxidation half-reaction, the reduction half reaction, the overall potential for the electrolysis, and the minimum voltage that must be applied to make the electrolysis occur.

B. Draw the electrolysis cell in detail. Zinc is plated onto a nail through reduction of zinc. If a current of 1.00 A is applied for 55 min to a nail with a surface area of 3.0 cm2, what is the thickness of the zinc that is deposited on the nail? The density of zinc is 7.1 g/cm3.
