Which base remains in the solution after the chlor-alkali process?
Answer and explanation
Correct answer: Sodium hydroxide
The chlor-alkali process is the electrolysis of concentrated aqueous sodium chloride, or brine. The products are chlorine gas, hydrogen gas, and sodium hydroxide solution; the sodium hydroxide is the alkali that remains in the solution. Thus option C is correct. Calcium hydroxide, magnesium hydroxide, and ammonium hydroxide are different bases and are not the product formed in this process.
