A neutralizing agent is a substance that helps to balance the pH of a solution. Synonyms for the term "neutralizing agent" include "alkali", "buffer", "neutralizer", "antacid", "acid neutralizer", and "neutralizing compound". These agents can be used in a variety of settings, including industrial processes, medical treatments, and household cleaning. In chemistry, neutralization reactions involve combining an acid and a base with the resultant solution often requiring a neutralizing agent to adjust the pH. Regardless of the setting, neutralizing agents are a critical component in maintaining balance and stability in a system.
