This field encompasses:

* Properties and reactions of acids and bases: This includes understanding their pH values, how they react with each other, and how they interact with other substances.

* Acid-base titrations: This is a technique used to determine the concentration of an unknown acid or base solution.

* Buffers: These are solutions that resist changes in pH when small amounts of acid or base are added.

* Acid-base indicators: These are substances that change color depending on the pH of a solution.

* Acid-base reactions in biological systems: This includes the role of acids and bases in maintaining the pH of blood, the function of enzymes, and the digestion of food.

While "acid-base chemistry" is the most comprehensive term, you might also hear it referred to as:

* Acid-base theory

* Acid-base reactions

* Acid-base equilibrium

These terms are used to focus on specific aspects of the study.
