The method used to determine the equivalence point of an acid-base solution is called: neutralization precipitation titration hydration

Titration

Explanation:

Neutralization When an acid reacts with the base then it undergoes neutralization to form a salt and water.

Precipitation: A precipitation reaction is a double displacement reaction one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) and thus as precipitates are formed, the reaction is called as precipitation.

Titration is the process where an acid or a base is titrated against a base or an acid so as to know the equivalence point.

Hydration is the surrounding of water molecules around the ions due to attraction between opposite charges.
