  1. Lab Quiz Acids and Bases Titration of Vinegar

  2. 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:

  3. 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

  4. 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%
