Final answer:
The most common neutralizers contain sodium chloride, which is used in various applications such as acid-base reactions, wastewater treatment, and household cleaners.
Step-by-step explanation:
The most common neutralizers typically contain sodium chloride. Sodium chloride is a compound made up of sodium and chlorine ions, and it is often used as a neutralizing agent in various applications, such as in acid-base reactions, wastewater treatment, and as an ingredient in household cleaners.
For example, sodium hypochlorite is a common neutralizer found in household bleach. When sodium hypochlorite is added to an acidic solution, it reacts with the acid to produce salt, water, and chlorine gas.
