When a buffer solution is prepared, the pH of the solution is adjusted to get it within the correct effective range. Typically a strong acid, such as hydrochloric acid (HCl) is added to lower the pH of acidic buffers. A strong base, such as sodium hydroxide solution (NaOH), is added t...

When an acid or a base is added, this area is the most effective at resisting big pH shifts. The capacity of a buffer is visually demonstrated by a titration curve. Because the addition of base or acid has no significant effect on the pH of the solution, the middle half of the curve...
Buffer definition: an apparatus at the end of a railroad car, railroad track, etc., for absorbing shock during coupling, collisions, etc.. See examples of BUFFER used in a sentence.
This shows that pKa and pH are equal when half of the acid has dissociated. The buffering capacity of a species or its ability to maintain pH of a solution is highest when the pKa and pH values are close. So, when selecting abuffer, the best choice is the one that has a pKa value...
