Orange juice is an aqueous solution that derives much of it's acidity from citric acid. There are variations in the acidity of each brand depending on many factors. Use the data below from an acid-base titration with standard NaOH (sodium hydroxide) to determine the mass% and molarity of citric acid in the juice sample.
citric acid H3C6H5O7
volume of juice: 2.7mL
Molarity of NaOH: .0115
Buret initial: 2.5mL
Buret final: 34.3mL
density of juice: 1.0g/mL
