A solution of phosphoric acid (~0.1M) is titrated with sodium hydroxide (0.2M) while measuring electronically the pH variation. Phosphoric acid is one of several weak acids that exist in carbonated beverages.

ABSTRACT In order to determine the phosphoric acid content in cola beverages, an acid base titration was used. Cola drinks contain phosphoric acid Phosphoric acid and its salts account for 25% of all the acid used in the food industries. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S>> The phosphoric acid content is usually quite low, so good technique is critical. Active 2 years, 11 months ago. Phosphoric acid (H 3 PO 4), a triprotic acid, is a common ingredient in cola drinks. POTENTIOMETRIC AND SPECTROPHOTOMETRIC DETERMINATION OF PHOSPHORIC ACID CONTENT IN SOME BEVERAGES * 1. In cola products, these acids are predominantly carbonic acid (from the carbonated water) and phosphoric acid. Click "Resources" below for a PDF of the experiment. Abstract The main objective of this experiment was to determine the concentrations of a polyprotic acid that is found in most soft drinks. Use your printed graph and data table to confirm the volume of NaOH titrant you recorded before and after the large increase in pH values upon the addition of 0.5 mL of NaOH solution. Kₐ₁ of Phosphoric Acid by Titration. 1. P.I. Phosphoric acid is a weak acid. It is about 10-5 in weaker acid in the second and very weaker in the third ionization about 10-5. The concentration of phosphoric acid in cola drinks is dependent on pH: H 3 PO 4 + OH− −= H 2 PO 4 + H 2 O H 2 PO 4− −+ OH = HPO 42− + H 2 O HPO 4 $_C�JXd�&3��4K287*��@�Z�J#�+�R�n����8� G/���#��:�n(�q�3���ܮ�0k�}�r�Z9�|�� Phosphoric acid is a weak acid in the first ionization step since it does not ionize completely in the aqueous solution. https://doi.org/10.1021/acs.jchemed.9b00025, https://doi.org/10.1021/acs.jchemed.7b00618, https://doi.org/10.1021/bk-2016-1221.ch003, https://doi.org/10.1016/j.xphs.2016.10.008, https://doi.org/10.1080/10511970601131571, https://doi.org/10.1016/S0021-9673(00)94146-3. The assessment of the content of phosphoric acid in cola type drinks is carried out through a potentiometric titration because the intense color of the soft drink makes difficult the use of pH indicators to identify the equivalence point, which are based on the use of vision human for the determination of color change. Concentrated phosphoric acid can be titrated directly by volumetric titration without problems. No. Nicholas Therefore, the amount of phosphoric acid can be determined in a simple titration process. If the strong base is used to titrate the polyprotic acid, the titration reaction takes place in steps. Your Mendeley pairing has expired. 1. Educ.
