It is a component of all cola soft drinks. ABSTRACT In order to determine the phosphoric acid content in cola beverages, an acid base titration was used. Therefore, the amount of phosphoric acid can be determined in a simple titration process. Abstract The main objective of this experiment was to determine the concentrations of a polyprotic acid that is found in most soft drinks. How Much Cranberry Juice Is in Cranberry–Apple Juice? Given that 20.00 mL of phosphoric Acid solution required 15.50 mL of 0.200M NaOH for the first equivalent point. 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. 15.
