Example 1.

The industrial production of aluminum uses a current of 25 000 amps. Calculate the number of hours required

to produce 10 kg of aluminum from the electrolysis of molten aluminum oxide. ( 1 mole e- = 96500 A ∙ s )

Solution

Al3+ + 3e-  Al

10 kg Al ( 1 kmol Al / 27kg )(3 kmol e-/1 kmol Al)(96500 A ∙ s/1 mol e-)(1/25000 A)(10000)(1 hr/3600s) = 1.19 hr

II. SODIUM INDUSTRY

Sodium is a very reactive metal first discovered by Sir Humphry Davy in 1807. This element is extracted by

electrolysing molten sodium chloride in the Down's cell.

A. USES

Sodium is used for the production of sodium borohydride, sodium azide, indigo,

and triphenylphosphine. Furthermore, it can be utilized as alloying metal, an anti-scaling agent, and as a

reducing agent for metals when other materials are ineffective. Sodium vapor lamps are often used for street

lighting in cities and give colours ranging from yellow-orange to peach as the pressure increases. It is also used

as a desiccant; it gives an intense blue colouration with benzophenone when the desiccate is dry. It also play an

important role in organic synthesis since it is widely used in various organic reactions such as the Birch reduction,

and the sodium fusion test which is conducted to qualitatively analyze compounds. In a more advanced

technology, it is used to create artificial laser guide stars that assist in the adaptive optics for land-based visible

light telescopes.
