Neutralization (chemistry) - Wikipedia

In chemistry, ,neutralization, or neutralisation is a chemical reaction in which ,acid, and a base react quantitatively with each other. In a reaction in water, ,neutralization, results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the ,acid, strength of the reactants. Animation of a strong ,acid,–strong base ,neutralization, titration. The …

To prevent the sulfur dioxide from being released, a ,device, known as a scrubber gleans the gas from smoke stacks. This ,device, first blows calcium carbonate into the combustion chamber where it decomposes into calcium oxide (lime) and carbon dioxide. This lime then reacts with the sulfur dioxide produced forming calcium sulfite.
