Pools using chlorine gas as a disinfectant produce hydrochloric acid, which can be neutralized with:

  1. chlorine tablets

  2. hydrogen peroxide

  3. muriatic acid

  4. soda ash

The correct answer is: soda ash

Hydrogen peroxide is not a base and would not neutralize the pH of the hydrochloric acid produced. Muriatic acid is another name for hydrochloric acid, so it would not be used to neutralize itself. Chlorine tablets are also not a base and would not neutralize the hydrochloric acid. Therefore, the most appropriate and correct choice is option D soda ash, a common alkaline material used for pH adjustment in pools. It reacts with the hydrochloric acid to form water and a salt, effectively neutralizing the acid.
