Buffer Solution

A detailed Summary of Buffer Solution


Buffer solution is a solution that resists changes in pH. Buffer solutions can occur either at acidic or basic pH. An acidic buffer solution consists of a solution of a weak acid and its conjugate base, for example ethanoic acid and sodium ethanoate. A basic buffer solution consists of a solution of a weak base and its conjugate acid, for example ammonia and ammonium chloride. If the added solution varies with the pH value of the original buffered solution, the pH of the final solution will remains unchanged, provided that the buffer is not full. Buffer solutions provides its buffering effect mainly based on the effect of chemical equilibrium. Buffer solutions is an essential kind of reagent in many biological processes involving living organisms as well as many modern chemical industrial processes.

Typically a buffer solution contains a weak acid and its conjugate weak base in approximately equal concentrations, with both components present in appreciable amount. For example, if we need to prepare a buffer solution in the laboratory, we can do so by mixing ammonium chloride (NH4Cl) and ammo
