Explanation:
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

Answer:
acid : A chemical term for sour materials that have a pH below 7.0 (on a 14-point scale). Acids often are capable of eating away at some minerals such as carbonate, or preventing their formation in the first place. Chemically, acids are known for having the ability to either donate a proton (hydrogen ion) to another compound or to accept a pair of electrons. The first is known as a Brønsted-Lowry acid. Chemists refer to the second type as a Lewis acid.
base : (in chemistry) A chemical that can accept protons from hydrogen molecules, or donate a pair of electrons. Basic solutions are also referred to as alkaline.
