2. Electrolysis
• Is a decompotion
reaction from
compound into it’s
element using the
electrical current.
3. Brine . . .
• Is a concentrated aqueous
solution of sodium chloride
or a solution of sodium
chloride (NaCl) and water
(H2O).
4. • The electrolysis of brine is a large-scale
process used to manufacture chlorine
from salt. Two others useful chemicals
are obtained during this process, they
are Sodium Hydroxide (NaOH) and
Hydrogen gas (H2). This process is called
the electrolytic (chloralkali) process.
5. Brine Electrolysi
• So, brine electrolysis is where a solution of sodium
chloride (common stable salt) dissolved in water is
decomposed into chlorine gas, hydrogen gas,
hydroxide ions, and sodium ions by passing electrical
current through the solution.
• H2 will pumped off at cathode compartment and Cl2 at
anode compartment. The two ions produced (OH- and
Na+ ) will combine to form a solution of sodium
hydroxide (NaOH), a very strong alkali which has many
applications.
10. Uses I
Sodium Hydroxide
Industry
also known as
caustic soda : processing food
products, removing pollutants from
water, strong chemical base in the
manufacture of pulp and paper,
textiles, drinking water, and
detergents. also the most common
base used in chemical laboratories.
11. • Chlorine : Disinfectant and purifier,
manufacture of hydrochloric and making
plastics.
• Hydrogen : rocket fuel, manufacturer of
hydrochloric acid and potential as a
pollutant free fuel
