Electrolysis of NaCl solution with inert electrodes for certain period of time gave 600 cm³ of 1.0 M NaOH in the electrolytic cell. During the same period 31.80 g of copper was deposited in a copper voltameter in series with the electrolytic cell. What is the percent current efficiency in the electrolytic cell? (At. wt. of Cu = 63.6)

Q.5. Aluminium having oxidation potential 1.66 V is expected to be readily oxidized in air but in actual practice aluminium undergoes a very slow chemical corrosion. Why?
