Explain the chlor - alkaline process and write one use of each product.....
Answers
Answer:
When electricity is passed through an aqueous solution of sodium chloride (brine) Hindi composes to form sodium hydroxide process is called chlor-alkali process because of the products formed chlor for chlorine and alkalis for sodium hydroxide.
Chlorine gas is given off at anode and nitrogen gas at the cathode. sodium hydroxide solution is formed at the cathode.
Uses of:
hydrogen gas- Fuel, Ammonia for
fertilizer
Chlorine gas- Water treatment, disinfectant, pesticides
NaOH- degreasing metals,Paper making
Answer:
Hello ✌️
Explanation:
The chlor-alkali industry uses brine (salt water) to produce chlorine, sodium hydroxide (NaOH or caustic soda), and hydrogen. An electric current is passed through the brine, to form hydrogen gas at the negative electrode and chlorine gas at the positive electrode, leaving a solution of sodium hydroxide.
The three products are : Sodium hydroxide (NaOH), Chlorine (CID and Hydrogen (H2).
NaOH - for soaps and detergents and paper making or artificial fibres.
Cl2 - PVC, pesticides, CFCs.
H2 - fuels, margarine, NH3 for fertilizers
