A buffer is a solution encompassing a weak acid and its conjugate base in alike amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases. This primarily consist of compounds that stabilize the pH of a solution by removing or replacing hydrogen ions. Also, substances that resist change in pH.
