Acid,-,neutralizing, capacity or ANC in short is a measure for the overall buffering capacity against acidification for a solution, e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below), or dynamically as the amount of ,acid, needed to change the pH value from the sample's value to a chosen different value.

The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water (H2O), it is more specifically a neutralization reaction.
