Question

What is a buffer solution?

Answer 1

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solutionconsisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acidor base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. In nature, there are many systems that use buffering for pH regulation. For example, the bicarbonate buffering system is used to regulate the pH of blood
