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.

This term is ,used, interchangeably with ,acid,-neutralizing capacity (ANC) ⁷. If a body of water has a high alkalinity, it can limit pH changes due to ,acid, rain, pollution or other factors ⁸. The alkalinity of a stream or other body of water is increased by carbonate-rich soils (carbonates and bicarbonates) such as limestone, and decreased by sewage outflow and aerobic respiration.

First, the compounds in the water such as bicarbonates neutralizes the acids being added. The more ,acid, is being added, the bicarbonates get “,used, up” as they are neutralized by the ,acid,. Until eventually, all the ,acid,-neutralizing compounds are ,used, up. After this, an ,acid, in the water will lower the pH in a linear way.
