Question

In the chlor-alkali process, we obtain a mixture of
(a) sodium hydroxide and chlorine gas.
(b) sodium hydroxide and hydrogen gas.
(c) hydrogen and chlorine gases.
(d) sodium hydroxide, chlorine gas and hydrogen gas.​

Answer 1

Answer:

D) Sodium Hydroxide ,

Chlorine gas , Hydrogen

gas.

Explanation:

In Chlor alkali process electrolysis of aqueous sodium chloride(NaCl) solution [ known as brine solution] take place .

Reaction Involved in this process is as follows:-)

$2NaCl + 2H_2O \implies Cl_2(g) + H _2(g) + 2NaOH$

So

Sodium Hydroxide hydrogen gas and chlorine gas are formed in Chlor Alkali process.

Answer 2

$\Large{\underbrace{\underline{\bf{ANSWER\:}}}}:$

(d) Sodium hydroxide, Chlorine gas and Hydrogen gas.

Chlor-alkali Process

➵ When electricity is passed through an aqueous solution of sodium chloride (brine), it decomposes to form sodium hydroxide. This process is called chlor-alkali process.

$\dagger\:\sf{2NaCl\:_{(aq)}\:+\:2H_2O\:_{(l)}\:\longrightarrow\:2NaOH\:_{(aq)}\:+\:Cl_2\:_{(g)}\:+\:H_2\:_{(g)}}$

$\Large\bf\therefore$ As a result of the above reaction sodium hydroxide (NaOH), chlorine gas (Cl₂) & hydrogen gas (H₂) are formed.
