Consider the following electrochemical cell:

Answer the following questions:

(a) Draw a schematic of the cell.

(b) Write the oxidation and reduction half-reactions.

(c) Calculate the pH in the electrolyte when the cell potential is E = 0.244V; when E =Corrosion of steel in concrete can be described by the following shorthand notation: 0.717 V.

(d) Describe how an electrochemical cell can be used as a pH sensor.
