What is produced in the electrolysis of brine?
chlorine gas and sodium only
chlorine gas and oxygen gas only
chlorine gas and hydrogen gas only
chlorine gas, sodium hydroxide, and hydrogen gas

chlorine gas, sodium hydroxide, and hydrogen gas

Explanation:

The electrolysis of the sodium chloride NaCl solution (brine) will produce chlorine Cl₂ gas and solid sodium Na.

After that, because the reaction takes place in water solution,  metallic sodium will react with water forming sodium hydroxide and hydrogen gas.

Na + H₂O → NaOH + H₂

Option D. The electrolysis of brine produces chlorine gas, sodium hydroxide, and hydrogen gas.

Explanation:

Brine is a solution sodium chloride and water. Electrolysis is a process in which a chemical solution is put under an electric current in order to produce chemical changes and bring a new chemical solution as a result. Industries use electrolysis of brine in a large scale in order to produce chlorine from salt, but chlorine gas is not the only product of the electrolysis of brine, as this process also makes sodium hydroxide and hydrogen gas.
