Your lab assignment presentation involves putting together a PowerPoint presentation to show other students how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations.
To do this presentation (minimum 6 slides, in PowerPoint format), we are providing you with an acid, acetic acid (HC2H3O2) and the base (NaOH), and you will use phenolphthalein as an indicator.
Create a 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 (consult your instructor if you need further clarification). At the end of your presentation (only PPT slides), you will calculate (1) the unknown concentration of the acetic acid (Molarity) and (2) the % mass/vol of the Vinegar solution.
Here is a video that illustrates the titration process and necessary calculations:

Here is the hypothetical experimental data that was obtained after your hypothetical titration. Use the data provided for your calculations:
Part 1: Title page
Purpose of a titration, what is titration and why do we perform a 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 with examples). Note: this section should provide insightful discussion).
Instrumentation – what are the instruments and glassware used when performing a titration.
Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment.
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 for the Molarity of the acetic and the % of the acetic acid. Your results must include the following step-by-step calculations:
