Question

To learn about titration types and how to calculate pH at different points of titration. In an acid-base titration, a titrant (solution of a base or acid) is added slowly to an analyte (solution of an acid or base). The titration is often monitored using a pH meter. A plot of pH as a function of the volume of titrant added is called a pH titration curve. Prior to the titration, the pH is determined by the concentration of the analyte. When the titrant is added, it begins to neutralize the analyte. The decrease in the analyte concentration changes the pH. At the equivalence point, equivalent quantities of acid and base have been mixed together such that the acid-base reaction is complete, and the pH is determined by the product. In the case of a strong acid-strong base titration, the salt formed is neutral, and pH=7. In a weak acid-strong base titration, a basic salt is produced, and pH>7. In a weak base-strong acid titration, the salt is acidic, and pH<7. After the equivalence point, the pH is determined by the concentration of excess titrant.
