a) Buffer
b) Acid
c) Base
d) Isotope

Answer 1

A molecule that binds up excess hydrogen ions in a solution is called a buffer.

Step-by-step explanation:

A molecule that binds up excess hydrogen ions in a solution is called a buffer. Buffers are solutions that moderate pH changes when an acid or base is added to the buffer system. They help maintain a constant pH level. An example of a buffer system in the human body is the bicarbonate system.
