Biology is brought to you with support from the Amgen Foundation. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. Acids bases and pH.
The protection is afforded by the presence in the solution of a weak acid and related salt for example acetic acid and sodium acetate which maintains the equilibrium by means of ion transfer and neutralization. A buffer may also be called a pH buffer hydrogen ion buffer or buffer solution. Substance or group of substances that tend to resist pH changes of a solution thus stabilizing its relative acidity and basicity.
