Here is a video that illustrates the titration process and necessary calculations: https://www.youtube.com/watch?v=9pS7Q4MQCYI You must show all your step-by-step calculations with proper formulas, units, and significant figures (for finals answers for Molarity of Acetic Acid and % Mass of Acid in Vinegar) review Chapter 2 for multi-step calculations: addition/subtraction: fewest decimal places multiplication/division: fewest significant figures You can either type your calculations and answers (which might be time-consuming) or write them on the paper/digital tablet and insert them as pictures in the slides. Make sure they are easily read. Concentration of NaOH (from the bottle): __0.350 M___ The volume of vinegar used (that you poured in the flask): __9.50 mL____ Average volume of NaOH used (mL): Average volume of NaOH used (L): Moles of NaOH used in titration: Moles of HC2H3O2 neutralized by NaOH: Molarity of HC2H3O2 (M): Grams of HC2H3O2 (g): Percent (m/v) of HC2H3O2 in vinegar (%): mock titration experiment and use given hypothetical data (volume of vinegar, Molarity of NaOH and volume of NaOH for three trials) to solve the titration calculations you will calculate (1) the unknown concentration of the acetic acid (Molarity) and (2) the % mass/vol of the Vinegar solution.

• Your presentation must consist of more than merely a series of bullet points to earn full credit.
. Remember, you want to teach your peers how to do titration experiment and calculations. Your experiment should
be reproduced with ease.
. Use the Notes section for each slide to fully explain your answers, if necessary.
• Turnitin will be used, so paraphrase where necessary to avoid plagiarizing.
• Grading: See rubric for specific grading criteria (in My Grades). You will be graded based on the rubric; therefore, carefully
read it before you start creating your assignment. Remember there are 50 points, so your work must show quality and
effort.
