ELI5: A buffer is made up of two types of molecules: an acid and a base. A key feature is that the acid and base are "alternative" forms and the two can switch back and forth. A buffer can resist pH change due to the presence of both molecules. When you add a new acid, it reacts with the base and becomes neutralized. how do you cite a photo in a powerpoint apa

"WebApr 12, 2024 · A buffer solution that contains large quantities of a weak acid, and its salt with a strong base, is called an acid buffer. On the acidic side, such buffer solutions have pH, i.e.pH is below 7 at 298 K. The equation gives the pH of an acid buffer.
