What is a pH buffer and how does it work? – WisdomAnswer

WebA solution whose pH is not altered to any great extent by the addition of small quantities of either an acid or base is called buffer solution. Buffer is also defined as the solution of reserve acidity or alkalinity which resists change of pH upon the addition of a small amount of acid or alkali. WebBuffers are broadly divided into two types – acidic and alkaline buffer solutions. Acidic buffers are solutions that have a pH below 7 and contain a weak acid and one of its salts. For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75. Alkaline buffers, on the other hand, have a pH above 7 ...

Table of Contents show. WebBest. [deleted] • 8 yr. ago. 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.

WebApr 1, 2024 · A buffer solution is a type of solution that barely changes its pH even if a small amount of acid or base is added to it. It acts as a neutraliser for both acid and base. It is a combination of weak acid and conjugate base or vice-versa. Why is pH balance important? What are buffer solutions used for? What is the pH of a buffer solution?
