Abstract

By studying a number of soft drinks with color but with or without phosphoric acid, the authors have determined that the required 20-fold dilution required in the “Determination of Phosphorus in Cola Drinks” is not to dilute the color but merely to place the sample within the calibration range of the analysis.
