Definitions:

Anion

An anion is a negatively charged ion, meaning it has more electrons than protons, which is typically formed when an atom gains one or more electrons.

Acetic Acid Solution

A solution composed of acetic acid, often used in vinegar, with acidic properties resulting from the presence of acetic acid.

Buffer Solution

A solution that resists changes in pH upon the addition of small amounts of acid or base, typically made from a weak acid and its conjugate base.

Acid

A substance that can donate a hydrogen ion (H+) and usually has a sour taste.
