Titration curves and indicators

WebMar 7, 2024 · The titration curves of weak acid titrated with strong base and weak base titrated with strong acid are inverse of each other. These curves are shorter than the titration curves with strong acid and strong base. The shape of the titration curve of a weak acid or weak base depends heavily on their identities and the Ka or Kb. WebAcid-Base Titration can be defined as a method of quantitative analysis that is used for determining the concentration of an acid or base. This concentration of an acid or base is determined by neutralizing it with a standard solution of base or acid having a known concentration. In Acid-Base Titration, an acid is titrated with a base, and a base (alkali) is …
