Buffers
A) are strong acids or bases.
B) keep the pH within normal limits.
C) release large amounts of hydrogen ions (H+) .
D) will only lower the pH.
E) will only increase the pH.
Buffers
Substances that minimize changes in the pH of a solution by absorbing or releasing hydrogen ions.
pH
A logarithmic scale used to specify the acidity or basicity of an aqueous solution, ranging from 0 (very acidic) to 14 (very basic) with 7 being neutral.
Hydrogen Ions
Positively charged ions (H+) that contribute to acidity or alkalinity of solutions and play critical roles in many biological processes.

Final Answer :
B
Explanation :
Buffers are solutions that resist changes in pH when small amounts of acid or base are added. They contain a weak acid and its corresponding conjugate base (or a weak base and its corresponding conjugate acid) which can absorb any added H+ or OH- ions to maintain the pH within normal limits. Buffers are not strong acids or bases and do not release large amounts of hydrogen ions. They can increase or decrease the pH depending on the initial pH and the ratios of the weak acid and its conjugate base in the buffer solution.
