WebA 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 … WebBuffer Solutions. A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base, in relatively equal and "large" quantities. Calculations are based on the equation for the ionization of the weak acid in water ...

WebWhat is meant by buffering a circuit is using a buffer in a circuit. Using a buffer in a circuit achieves an important effect in the circuit. A buffer is basically a high-impedance device that accepts a voltage input and … WebA buffer is a solution that resists changes in pH. They are most commonly formed by the addition of a weak base or weak acid to water. Weak bases and acids must be used (as opposed to strong bases and acids) since they exist in equilibrium. This means that the conjugate pairs of both the acid and base exist in the solution.
