CH 111 – Exp. 6 Titration of Fruit JuiceData SheetThis experiment is highly similar to the titration of HCI withNaOH so there is no video accompanying this lab. In thistitration 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 bigdifference between citric acid and HCI is that citric acid istriprotic, meaning it has three protons (H') to donate, so asyou can see in the balanced chemical reaction below, itwould take 3 times as many moles of NaOH to neutralizethe H,C,H,O,. This makes the molar ratio ofH,C,H,O,:NAOH is 1:3, and it is reflected in the calculationsshown below. For this experiment, we assume that all ofthe acid present in the fruit juice is citric acid to actuallymake the calculations possible.H3C6H5O7 (aq) + 3 NaOH (aq)Na,CsH5O7(aq) + H20 (aq)Citric AcidTrial 1 Trial 2 Show CalculationsVolume Fruit Juice (mL)20.0 20.0Molarity NaOH (M)0.110Volume NaOH initial (mL)0.4 0.6Volume NaOH final (mL)19.8 20.5Volume NaOH used intitration (mL)Moles NaOH (mol)Moles H,C,H,O, (mol)Mass H,C,H,O, (g)Mass H,C,H,O, in 1.0 mL ofjuice (g/mL)Average Mass in 1.0 mL ofjuice (g/mL)
