Description For this assignment, you need to “teach” how to do titration using hypothetical numbers. Concept, background, procedure, and calculations. To do this presentation (minimum 6 slides, in PPT), we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will create a mock titration experiment and use your own hypothetical data (volume of vinegar, Molarity of NaOH, and volume of NaOH for three trials) to solve the titration calculations (consult me, if you are in doubt). At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/vol of the Vinegar solution. Part 1 Title page Purpose of titration, what is titration and why do we perform titration? Include your thoughts on why understanding acid/base titration is important to your future career, and how you will use this concept as you complete your degree (at least 5 sentences and examples). Instrumentation – what are the instruments, glassware used when performing a titration. Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment (refer to Lab Manual pages 227-230) Your base concentration must have 3 decimals and your acid volume must have at least 1 decimal. Buret readings will give you two decimals. Observations and expectations – List the observations and write your expectations. This might include color change and when the equivalence point (endpoint) might be reached. Part 2 Calculations and Results. Show all your step-by-step calculations and write your results, the Molarity of the acetic and the % of the acetic acid. HINT: use Part A on page 233 as a template Remember sig figs in calculations to properly express your final answers (molarity and % mass): addition/subtraction -> fewest decimals multiplication/division -> fewest sig figs
