Phosphoric acid titration method
WebThe phosphoric acid concentration is measured during the manufacturing of the cola syrup and during the bottling of the cola drink. Citric acid is used for the same purpose and both of these acids may be used in combination. Traditionally, analysts perform a labor-intensive colorimetric assay to quantify the amount of phosphoric acid in soft ... WebAqueous acids, e.g. hydrochloric acid (37%), hydrofluoric acid (48%) or phosphoric acid, can be titrated directly by the volumetric method without problems. Due to the high concentrations of water only small sample sizes are required, which can …
