Question

How is sodium hydroxide manufactured in industries ? Name the process.
In this process a gas X is formed as by-product. This gás reacts with lime
water to give a compound Y, which is used as a bleaching agent in the
chemical industry. Identify X and Y and write the chemical equation of
the reactions involved.
​

Answer 1

Sodium hydroxide is produced using a salt water brine. The sodium and chloride are separated. ... These electrons are used to separate water into hydrogen gas andhydroxide. The hydroxide can then combine with the sodium ion to create sodium hydroxide.

Answer 2

Answer:

• In the process of "sodium hydroxide" (NaOH), "hydrogen gas" ($H_{2}$) and "chlorine gas" $Cl_{2}$ (X) are the by-products formed.
• Chlorine gas reacts with the lime water [$Ca(OH)_{2}$ ]to produce bleaching powder ($CaOCl_{2}$), a bleaching agent.
• Thus, X is 'chlorine gas' ($Cl_{2}$ gas). Y is calcium oxychloride or bleaching powder ($CaOCl_{2}$).

The chemical equation for the preparation of sodium hydroxide is as follows:

                            $2Nacl+2H_{2}O \rightarrow NaoH+Cl_{2}+H_{2}$

                                   $Cl_{2}+Ca(OH)_{2} \rightarrow CaCl_{2}+H_{2}0$

Sodium hydroxide is also called as caustic soda.

In one of the industrial process used for manufacture of sodium hydroxide, a gas ‘X’ is formed as by-product. The gas ‘X’ reacts with lime water to give a compound ‘Y’ which is used as a bleaching agent in chemical industry. Identify ‘x’ and ‘Y’ giving the chemical equation of the reaction.
