Carla Paulo Exercise 1 Acid-Base Titrimetry Purpose: To determine the percent of KHP in a solution and to determine the amount of acetylsalicylic acid in an aspirin tablet using a standardized solution of NaOH. Unknown #: KHP unknown: 1B Important Equations: KH 4 C 8 H 4 O 4 + NaOH NaKC 8 H 4 O 4 + H 2 0 C 9 H 8 O 4 + NaOH NaC 9 H 7 O 4 + H 2 O Safety Factors: Safety goggles and gloves must be worn because chemicals used in the reaction are corrosive and can cause burns. Handle glassware carefully. Raw Data: A. Standardization of NaOH Solution Trial 1 Trial 2 Trial 3 Mass of Vial Initial (g) 29.2800 28.6767 27.9850 Mass of Vial Final (g) 28.6767 27.9850 27.3777 Mass of KHP (g) 0.6033 0.6917 0.6073 Initial V (NaOH) (mL) 4.55 4.15 4.25 Final V (NaOH) (mL) 34.85 39.00 34.85 B. Determination of %KHP in an Unknown Trial 1 Trial 2 Trial 3 Mass of Vial Initial (g) 22.1089 21.2644 20.4303 Mass of Vial Final (g) 21.2644 20.4303 19.5197 Mass of Unknown (g) 0.8445 0.8341 0.9106 Initial V (NaOH) (mL)
