Buffer and volumetric solutions: A buffer solution contains a weak acid and its salt or a weak base and its salt. It resists changes in pH when a small amount of strong acid or base is added. Buffer solutions are used in various chemical reactions and natural systems to regulate pH levels. They have applications in industries such as paper production, pharmaceuticals, and food preservation. Blood acts as a natural buffer to maintain its pH at 7.4. In qualitative inorganic analysis, a CH3COOH + CH3COONa buffer is used to remove phosphate ions.
