Question

In the manufacture of bromine from sea water, the mother
liquor containing bromides is treated with
(a) carbon dioxide (b) chlorine
(c) iodine (d) sulphur dioxide

Answer 1

Answer:

Correct option (b) chlorine

Bromide in the mother liquor (containing MgBr2) is oxidised to Br, by passing Cl, which is a stronger oxidising agent.

Answer 2

In the manufacture of bromine from sea water, the mother  liquor containing bromides is treated with chlorine.

Explanation:

• Bromide is the mother liquor which oxidized to Br which passes Cl and the oxidizing agent is stronger.

• In sea water the soluble salts are found for the formation of bromine to recover more.
• 65 ppm of bromine are in sea water more concentrations are found in bromine in brine wells and inland seas.
• Bromine ions concentration in the solutions are 10 - 12 gr/l from Dead Sea. When concentration is more then the manufacturing bromine is efficient.
• Reaction of bromide with chlorine is the process for manufacturing bromine.
