Question

What happens when electricity is passed through brine? Write the chemical equation for it.

Answer 1

Hint: Brine is a highly concentrated solution of sodium chloride (\[NaCl\])in water (\[{H_2}O\]). Brine can refer to salt solutions ranging from about \[3.5\] percent (a typical concentration of seawater, on the lower end of solutions used for brining foods) to about \[26\]percent in various contexts (a typical saturated solution, depending on temperature).

Complete answer:
When electricity is passed through brine it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode. Sodium hydroxide solution is also formed near the cathode.
The chemical equation for the above decomposition is:
\[12.3 and 61.8\]
In this chemical reaction the chlorine and hydrogen gas are liberated in the surrounding while\[NaOH\] is obtained in aqueous form. Sodium Hydroxide( \[NaOH\]) is the basic solution obtained at last.
Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates \[NaOH\].n\[{H_2}O\]The monohydrate \[NaOH\].\[{H_2}O\] crystallizes from water solutions between\[12.3 and 61.8\] . The commercially available "sodium hydroxide" is often this monohydrate. Many everyday products contain sodium hydroxide, including paper, aluminum, commercial drain and oven cleaners, and soap and detergents.

Note:
Sodium hydroxide is used in the production of soaps and a variety of detergents used in both residential and commercial applications. By combining chlorine and sodium hydroxide, chlorine bleach is created. Sodium hydroxide-based drain cleaners convert fats and oils.
