Question

How is sodium hydroxide produced ? Write the balanced chemical equation also
Why is this process called as chlor - alkali process ? In this process name the
products given off at:
(a) anode
cathode
Write one use of each of these products.​

Answer 1

Answer:

sodium hydroxide produces s+ h2

Answer 2

Answer:

When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is called the chlor-alkali process because of the products formed- chlor for chlorine and alkali for sodium hydroxide. Following is the chemical equation for the process:

2NaCl(aq) + 2H2O(l) → 2NaOH(aq) + Cl2(g) + H2(g)

Products given off-

At anode, chlorine gas is liberated and at cathode hydrogen gas is liberated.

Uses-

Chlorine- Used as disinfectant in water treatment.

Sodium hydroxide- For production of soaps and detergents.
