Why is Alka Seltzer a good buffer?

When the tablet is placed in water, the citric acid reacts with the sodium bicarbonate, producing sodium citrate in solution and releasing carbon dioxide gas. Excess bicarbonate also neutralizes hydroxide ions, helping the solution to resist a change in pH. Alka-Seltzer now also contains aspirin, which is a weak acid.

Just so, is Alka Seltzer a buffer?

The Alka-Seltzer acts as a buffer. More base and acid is required to bring the Alka-Seltzer solutions to a basic or acidic pH. Concept: A buffer resists changes in pH when acid or base are added.

Subsequently, question is, why is potato a good buffer? It grows in the ground, so will see a lot of harsh conditions (variations in pH due to rain, soil, pollution, etc.) If it does not have a mechanism to keep those harsh conditions from changing the internal pH of the potato, it should die whenever it does not have ideal conditions.

Is milk a good buffer?

The same amount of acid would have a small effect on the pH of milk because milk proteins and salts neutralize the acidity. The two most important buffer components of milk are caseins (buffer maximum near pH 4.6) and phosphate (buffer maxima near pH 7.0).

How do buffers work?

A buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH. As the above example shows, a buffer works by replacing a strong acid or base with a weak one.

Does Alka Seltzer make birds explode?
