Interactive Example 4.14 - Neutralization Titration A student carries out an experiment to standardize (determine the exact concentration of) a sodium hydroxide solution To do this, the student weighs out a 1.3009-g sample of potassium hydrogen phthalate (KHC8H404, often abbreviated KHP) KHP (molar mass 204.22 g/mol) has one acidic hydrogen The student dissolves the KHP in distilled water, adds phenolphthalein as an indicator, and titrates the resulting solution with the sodium hydroxide solution to the phenolphthalein endpoint The difference between the final and initial buret readings indicates that 41.20 mL of the sodium hydroxide solution is required to react exactly with the 1.3009 g KHP Calculate the concentration of the sodium hydroxide solution

6 a b U d [Tutorial: Titration stoichiometry] This question will walk you through the steps of calculating the volume of titrant required to reach the endpoint based on the volume and concentration of analyte. Consider the standardization of NaOH by titration with C,H,O, according to the following chemical reaction: 3 NaOH(aq) + C,H,O,(aq) = Na,C,H,O,(aq) + 3 H₂O(l) Step 1: Evaluate the question. How many moles of aqueous sodium hydroxide (NaOH) will react to completely neutralize one mole of aqueous citric acid (C,H,O,)? Which equation will be most helpful for solving this problem? Calculate the volume in mL of a 0.200 M NaOH solution needed to neutralize 345 mL of 0.033 MC,H,O, standard solution. Based on the fact that NaOH is a strong base and C,H,O, is a weak acid, how would you describe the pH of the solution at the endpoint, where moles of base = 3 times the moles of acid?

Many chemical compounds contain impurities. Crude potassium carbonate (K2CO3) obtained from the chemical supplier is assayed for purity in the following way: 8.450 g of crude potassium carbonate is weighed out into a flask and dissolved in water. The final volume was completed to 0.500 L with distilled water. 20.00 mL sample is taken from this solution and placed in a flask. Potassium carbonate is then titrated to the equivalence point with 17.80 mL of 0.2050 M HCl solution. What is the percent purity of potassium carbonate in this sample? K2CO3 + HCl  KCl + H2O + CO2
