# PowerPoint presentation, show other students how to perform titration.

Background Info:
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.
You will 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:
Titration Experiment & Calculate the Molarity of Acetic Acid in VinegarLinks to an external site.
Here is the hypothetical experimental data that was obtained after your hypothetical titration. Use the data provided for your calculations:
Your instructor will provide data for steps 1 and 2:
Students must complete Steps 3-10 for their presentation results!
The concentration of NaOH (from the bottle):
__0.250 M___
The volume of vinegar used (that you poured in the flask): __7.50 mL____

(2)

15.70 mL
(3)
Volume (mL) of NaOH used

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.

you start creating your assignment. Remember there are 50 points, so your work must show quality and effort.
To include in your PPT presentation:
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:
