Los Angeles Valley College Acid Base Titration Presentation

The goal of your Signature Assignment is to show that you can compute properties of solutions and analyze and interpret data. You will create a PowerPoint presentation that shows the process of going through an acid/base titration like you would if you were in a physical lab.

Due: Tuesday 08/10/21

Background Info:

Dear Students,

Your lab assignment presentation involves putting together a PowerPoint presentation to show other students on 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 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.

• Your presentation must consist of more than merely a series of bullet points to earn full credit
• Remember, you want to teach your peershow to do titration experiment and the calculations. We would be able to reproduce it with ease.
• Use the Notes section for each slide to fully explain your answers.
• 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 it is 100 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 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. Week 7 lab answer key download
