Unformatted text preview: moles of NaOH used to titrate the soda, to find H 3 Cit. Because there is 1 mole H 3 Cit to 3 moles NaOH, the moles of NaOH is multiplied by 3and then divided by the liters of soda used, which is 0.01 L. The result is the molarity of H 3 Cit. H 3 Cit (aq) + 3NaOH (aq) Na 3 Cit (aq) + 3H 2 O (l) 3. Acid Concentration in Soda . The acid concentration of soda is 0.08199 ± 0.00091 M. The reported uncertainty is acceptable because of the small standard deviation. 4. Acid Content in Other Consumables . The acid concentration of an orange is 0.0001 M and a lemon, 0.1 M. The acid concentration of soda is between that of an orange and lemon, two fruits which are none to be harmful to teeth, so soda must be harmful as well. 5. Effects of the Carbonation . Carbonation must be removed from the soda prior to the titration because the escape of a gas from the solution removes ions, which are the basis of pH....
