Pipet 10 mL portions of this solution into 250 mL beakers, add 40 to 50 mL of water to each, and titrate with 0.1 M NaOH. Potentiometric titration is the most common approach for automated titrations. In combination with automated sample preparation, it has both increased efficiency and reduced manual work load in many pharmaceutical labs. Potentiometric titrations involve the measurement of the potential difference between two electrodes of a suitable cell; conductometric titrations, the electrical conductance or resistance of the solution being titrated; and amperometric titrations, the electric current passing during the course of the titration.

Generally, electrolyte solution is used as an analyte. The appropriate set-up for a potentiometric titration is shown on Figure Page, Expt. 17, along with the details of glass and calomel electrodes. Potentiometric titrations (See Tro, Chapters 16 and 17, especially pp 795-805.) Figure 1 on the next page shows a plot of pH versus volume of base added for the titration of a strong acid with a strong base.

Therefore potentiometric titration is preferred over manual titration. 3.2 Potentiometric titration 16 . 3 TITRATION Titration is process of chemical analysis in which the quantity, amount or The first method comprised a manual complexometric titration, and the second comprised a potentiometric titration performed with an automatic titrator, obtaining sensitivity values of 0.0534% and 0.0038%, respectively, precision expressed in RSD% values below than 1%, and accuracy in recovery percentage greater than 99%. Figure 2. Titration curve from experimental potentiometric titration. (pH data versus the volume readings of the base.

Figure 2. Titration curve from experimental potentiometric titration. (pH data versus the volume readings of the base. On the graph shown above the weak acid only partially dissociates from its salt. The pH raised normally at first, but as it reaches a zone where the solution seems to be buffered, the slope levels out.

From the resulting titration curves, you will determine the concentrations of the acidic solutions as well as the acid-ionization constant of a weak acid. Introduction Redox titration of iodine in povidone iodine using thiosulfate In an iodine redox titration, starch, which turns blue-black in the presence of iodine, is typically used as the indicator. However, this method can be challenging for students because of the low solubility of iodine in water and the pH dependence of the reaction (which proceeds quantitatively in neutral or slightly acidic POTENTIOMETRIC TITRATION It’s a volumetric method in which potential between two electrodes (reference & indicator) is measured as a function of added reagent volume. 33.
