Definition - What does Neutralization mean?

Neutralization is the process of making a chemical reaction less effective by adding a neutralizer. The process helps in mitigating chemical reactions and preventing damage when chemically reactive materials come in contact with each other. The neutralization process prevents acidic well water from creating blue-green stains and lead from leaching into drinking water. It also prevents pinhole leaks in copper wires.

Petropedia explains Neutralization

High pH content in any acidic medium may damage the cost-intensive infrastructure of the oil and gas industry. Thus, neutralizing such acidic fluid or medium becomes necessary. One common neutralizer is calcite. When properly applied, calcite corrects pH levels of acidic medium and lets the levels reach a non-corrosive equilibrium. Upon contact with calcite, acidic water slowly dissolves the calcium carbonate, raises the pH level and reduces the potential leaching of copper, lead and other metals found in pipelines and other sophisticated industrial system. Depending on pH, water chemistry and service flow, the calcite bed must be periodically replenished as the calcite is depleted.

Similarly, masonry neutralizer or concrete neutralizer removes acid from walls so that the paint does not peel off. It is normally used on newly plastered concrete or after etching.
