A manufacturer makes lemon cordial by mixing flavoring, sugar syrup and citric acid. The concentration of the citric acid is determined by titration with NaOH. The sodium hydroxide solution is prepared by dissolving 4.000g of NaOH pellets in water to give 1.000L of solution. This solution is standardized by titrating 25.00ml with a0.1011M standardized solution of HCl. The average titration volume is found to be 24.10mL. To analyze the lemon cordial 50.00mLof the cordial is diluted to 500.0mL. Then 25.00mL of the diluted solution is titrated with the NaOH solution to the phenolphthalein endpoint.The following data were collected during one of the analysis runs of the lemon cordial. TITRATION #1 26.55 mL TITRATION #2 27.25 mL TITRATION #3 27.30 mL TITRATION #4 27.20 mL Determine the concentration of citric acid in the lemon cordial.
