Buffering components
WebThis is useful in determining buffer capacity, or how much strong acid or strong base can be added to a buffer without significantly affecting the pH. Buffer Capacity. Buffer capacity is the measure of a buffer’s ability to resist pH change. This ability depends on the concentration of the buffer components, meaning the acid and its conjugate ... A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an acid or a base aqueous solution consisting 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 acid or 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, the…
