titration of citric acid in lemon juice with sodium hydroxide uses

Lab 9

Using the values above if titration requires 1 02 mmol of NaOH to reach the endpoint the sample must also contain 1 02 mmol of acetic acid If the volume of the vinegar used is 8 05 mL the molarity of acetic acid is 1 02 mmol / 8 05 mL = 0 127 M In this experiment a carefully measured volume of vinegar (V analyte) is placed into a beaker and the mass determined
