Chemical neutralization is a process where an acid and a base react to form water and a salt. This reaction typically occurs when the hydrogen ions from the acid combine with the hydroxide ions from the base, resulting in a neutral solution. The pH level of the solution moves closer to 7, which is considered neutral on the pH scale. Neutralization is commonly used in various applications, such as treating acidic waste or balancing soil pH. For example, lime can be added to acidic soil to neutralize it, improving conditions for plant growth. This process is essential in both environmental science and everyday life.
