Determination of concentration of Acetic Acid (Part 2B of lab). Data taken from fine titrations only. Note that data table should accommodate three trials: a. Volume of NaOH solution in the buret at the start (mL): b. Volume of NaOH solution in the buret at the end (mL): c. Volume of NaOH solution delivered to the flask (mL): d. Volume of Unknown Acid solution in the flask (mL) ( the same value for all 3 titrations): Calculations/Discussion Questions: Titration Tutorial Calculate the molarity of the HCl from the equation (C stands for concentration and V stands for volume; M stands for the molarity of the base, which is known): C(acid) = M(base) * V(base) / V(acid) Standardization of NaOH (Part 2A of lab): 1. Approximate molarity of the NaOH solution, 0.8 g in 200 mL H 2 O: 2. Amount of benzoic acid to be neutralized by 20 mL NaOH solution, in both moles and grams: 3. Actual mL NaOH solution delivered in three titrations: 4. Calculated average concentration of the NaOH solution: Determination of Concentration of Acetic Acid (Part 2B of lab): 1. Moles of NaOH dispensed in all three titrations: 2. Molar concentration of the acid (moles/L) in each titration: 3. Calculate the average acid concentration from the three titrations (mol/L): Refer to the Laboratory Report grading rubric found at the end of Lab 2, prior to submitting the report.
