In this titration orange juice is used as the acid in place of HCI. That is because most fruit juices are acidic, with citric acid (H,C,H,O,) being one of the more common acids, especially and not surprisingly in citrus fruits. One big difference between citric acid and HCI is that citric acid is triprotic, meaning it has three protons (H) to donate, so as you can see in the balanced chemical equation below, it would take 3 times as many moles of NaOH to neutralize the H,C,H,O,. This means the molar ratio of H₂CH₂O₂ NaOH is 1:3, and it is reflected in the calculations shown below. For this experiment, we assume that all the acid present in the fruit juice is citric acid to actually make the calculations possible. Data Final buret reading, ml Initial buret reading, ml Volume of NaOH (titrant) Molarity of NaOH: 0.1065 M Volume of Fruit Juice: 20.0 mL Results and Calculations H₂C,H,O, (ag) + 3 NaOH (ag) Na,C,H,O,(ag) + H₂O (ag) (Citric Acid) 80,5 Report Sheet 000 500 F4 1 0.00 16.80 Calculate the number of mL of NaOH required for the titration Calculate the number of moles of NaOH Calculate the number of moles of H,C,H,O, titrated Calculate the mass of H,C,H,O, present in the juice Calculate the mass of H,C,H,O, present per mL of juice Calculate the average mass of present per mL of juice Trial 2 16.80 33.12 1 Trial please fill in the blanks. Please label everything as labeled on the sheet so i know which answers belong to which box. Please write neat no cursive please. Thank you!! 2 In this titration orange juice is used as the acid in place of HCI.
