Weberror due to ionization interference could be observed depending on the combinations of coexisting elements and analyte elements. The result of the study on elemental … WebIt is a buffer because it contains both the weak acid and its salt. Hence, it acts to keep the hydronium ion concentration (and the pH) almost constant by the addition of either a small amount of a strong acid or a strong base. If we add a base such as sodium hydroxide, the hydroxide ions react with the few hydronium ions present.
