Answer:

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

Step-by-step 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.

Answer:

chlorine gas, sodium hydroxide, and hydrogen gas

Step-by-step 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 +
(1)/(2) H₂
