A buffer release base to neutralize acid
|
|
|
A buffer can act like a base is pH is acidic, and it can act like an acid if pH is basic
|
|
|
A buffer releases acid to maintain proper pH
|
|
|
A buffer forms both actions and anions to counteract acids

Detailed explanation-1: -They resist a change in pH upon dilution or upon the addition of small amounts of acid/alkali to them. The pH of Buffer Solutions shows minimal change upon the addition of a very small quantity of strong acid or strong base. They are therefore used to keep the pH at a constant value.
Detailed explanation-2: -A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
Detailed explanation-3: -Buffer solutions maintain a stable pH by neutralizing added acids or bases. They consist of a weak acid and its conjugate base, which exchange protons and hydroxide ions to form water. The Henderson-Hasselbalch equation expresses the pH as a function of the PKa and the ratio of the base and acid concentrations.
Detailed explanation-4: -A buffer solution is a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. The bicarbonate buffering system maintains optimal pH levels and regulates the carbon dioxide concentration that, in turn, shifts any acid–base imbalance.
Detailed explanation-5: -Buffers in the Human Body Together they help maintain the bloods pH at 7.4. If blood pH falls below 6.8 or rises above 7.8, one can become sick or die. The bicarbonate neutralizes excess acids in the blood while the carbonic acid neutralizes excess bases.
