Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

0.3456 g of a solid acid is dissolved in 50 mL of water in a flask and a few drops of phenolphthalein are added to the solution. A buret containing 0.2545 M NaOH is prepared with an initial volume of 10.50 mL. The acid is accidentally titrated with the base beyond the end point, so 1.52 mL of 0.187 M HCl are added to the flask. The titration with the base is continued to a final volume reading of 40.55 mL. Calculate the molar mass of the solid acid.
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?

Walter White requires a sulfuric acid (Strong acid) solution to use in a very important synthetic reaction. He finds a bottle labeled H2SO4, but by some strange turn of events, he cannot remember the concentration. He decides to perform a titration to determine the concentration of the H2SO4. He pours 22.20 mL of his unknown sulfuric acid solution into a flask and finds that it requires 29.50 mL of 0.57 M KOH (strong base) to reach the endpoint. What is the concentration of Walter White's sulfuric acid solution?
