CHEM 104 EXPERIMENT 3 TITRATIONS AND TITRATION CURVES PORTAGE SUMMER 2023 LATEST UPDATE 199% CORRECT VERIFIED AND GRADED A+ Title: Titrations and titration curves Purpose: The purpose of this to perform titration analyses, including neutralization titrations, which occur between an acid and a base. Procedure: After gathering the necessary supplies, it was decided that we would perform reactions between the following solutions: strong acid/strong base, weak acid/strong base and strong acid/weak base. Standardization titration of NaOH: Used a strong acid/weak base. We determine the molarity of the NaOH by titrating it against potassium hydrogen phthalate. The phenolphthalein indicator was added to the solution of NaOH in a beaker along with water. We expect the solution to change from colorless to pink. We then documented the total amount of NaOH added from the buret to establish the color change. KHC8H4O4 + NaOH NaKC8H4O4 + H2O Standardization titration of HCl: Used a strong acid/strong base. The starting color of the solution is a translucent light yellow. The indicator utilized in this experiment is bromothymol blue, which was added to a solution of HCl. The given molarity of NaOH is 0.130M. Our goal endpoint pH was ~7.0. The goal color change is yellow to blue. HCl + NaOH NaCl + H2O Standardization titration of vinegar: Used weak acid/strong base. For this experiment, we utilized weak acid vinegar & strong base NaOH. After obtaining 3.09 g of vinegar, we added the NaOH indicator via the buret until a pink color change was obtained. A total of 19.7 mL of NaOH was added. HC2H3O2 + NaOH NaC2H3O2 + H2O Standardization titration of ammonia: After obtaining a graduated cylinder, scale, & household ammonia, a beaker was place
