Data and Calculations: The Standardization of a Basic Solution and the Determination of the Molar Mass of an Acid A. Standardization of NaOH Solution Initial reading, HCl buret Final reading, HCI buret Initial reading, NaOH buret Final reading, NaOH buret Trial 1 Trial 2 Trial 3 25 mL B. Determination of the Molar Mass of an Unknown Acid Mass of vial plus contents Mass of vial plus contents less Sample 16.IS Mass less Sample 2 6.15g 0096g 0546g Trial 1 Trial 2 mL. Initial reading, NaOH buret Final reading, NaOH buret Initial reading, HCl buret Final reading, HCI buret 26f nt268 6.8 mL Processing the Data A. Standardization of NaOH Solution mL mL. Total volume HC mL Total volume NaOH (continued on following pa custom page 149Explanation / Answer
Total Volume of HCl:
Trial 1 : V = 25 mL
Trial 2 : V = 35 mL
Trial 3 : V = 45 mL
Total Volume of NaOH:
Trial 1 : V = 27.4 mL
Trial 1 : V = 39.2 mL
Trial 1 : V = 50.4 mL
Mass of Sample = 0.396 g
Molarity of HCl = (0.396 / 36.5) / (25/1000) = 0.434 M
Molarity of H+ = 0.434 M
Molarity of OH- = 0.434 x 25 / 27.4 = 0.396 M
