Acids and Bases Titration of Vinegar Lab Quiz Acids and Bases Titration of Vinegar

You CAN use your lab handout for help on quiz. Use the sample data (in the next slide) to calculate the answers to #1-5 of the lab questions:

Lab DATA to use for quiz *WRITE DOWN ON YOUR PAPER Avg volume of base (NaOH) used = 18.0 mL Concentration of base (NaOH) = 1.00 M Avg volume of acid (HC2H3O2) used = 20.0 mL

Questions 1. Calculate the normality of the vinegar sample. 2. Calculate the molarity of the vinegar sample. 3. Calculate the grams of HC2H3O2 in the sample. 4. Calculate the % acetic acid in the sample. The density of the vinegar is 1.0002 g/mL. 5. Calculate your percent error for percent mass of the acid. Actual value = 5.0%
