Question

pfaYour lab assignment presentation involves putting together a 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, 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 use the data given to you to be used as an example of how to solve the mathematical calculations. 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 1. Purpose of a titration, what is titration and why do we perform a titration? 2. Instrumentation- what are the instruments, glassware used when performing a titration. 3. Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment. 4. 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 1. Calculations and Results. Show all your calculations and write your results, the Molarity of the acetic and the % of the acetic acid. 2. Your instructor will provide guidance and examples for completing calculations for titration. This assignment should be in current APA Style with both a title slide and a reference list that includes all the sources used. At least two scholarly sources should be used (your textbook can be one of the sources).

Introduction to titration
Titration: It is a quantitative technique for determination of concentration (or strength) of an unknown solution by reacting it with another solution of known concentration (or strength).
Purpose of titration: It is used to determine concentration of an unknown solution by measuring the volume of the known solution needed to completely react with unknown solution.
Why do we perform titration?: It has certain applications:
Less time taken for analysis
More accurate as there is no loss of analytes or chemicals like in filtration, precipitation, decanting or other process.
No time consuming process is required like long term heating, drying, evaporation etc.
One can easily visualize the end point by colour change.
No sophisticated instruments are required.
Glassware and chemicals required
Burette	Pipette	         Conical flask	    Funnel	   Volumetric flask	   Beaker
Glassware required:
Chemicals required:
Known concentration solution of sodium hydroxide (NaOH), known concentration solution of potassium hydrogen phthalate, phenolphthalein as indicator, unknown solution of vinegar or acetic acid (CH3COOH). 
Theory and Chemical reactions
The reaction between acetic acid and sodium hydroxide takes place according to following chemical reaction:
CH3COOH	+	NaOH			CH3COO- Na+		+	H2O
Acetic acid provides a proton to the hydroxide ion and behaves as an acid in the interaction between acetic acid and sodium hydroxide. The hydroxide ion is a base that accepts a proton. Acetic acid and sodium hydroxide have a 1:1 stoichiometric relationship. The moles of acetic acid in a sample can easily be found if the number of moles of NaOH used to titrate a sample of acetic acid is known.
The indication of completion of the reaction can be observed by using phenolphthalein as a indicator.
