How Much Acetic Acid is in Vinegar?
Introduction
• Brief description of the goal in this experiment
• Standardization, titration technique, etc.
• Brief explanation of the chemistry (acid-base reaction) and the titration process.
• Oxalic acid/NaOH, Acetic Acid/NaOH
• Give examples!
Procedure
• Provide a clear description (in a paragraph style) of the procedures used during the course of the experiment; include concentration/volumes of solutions. This should be detailed enough that another group could duplicate your work.
• Molarities of solutions must be listed correctly.
• Proper subscripts and physical states are very important.
• Materials should be incorporated into your procedure, NOT simply listed out.
• Ex. 20 mL of NaOH was obtained in a 100 mL beaker.
Results
• Include all data (even if you think it is bad). Present the obtained results in a clear and well organized fashion (tables, charts, etc.).
• Include balanced chemical equations:
- Properly use of subscripts and physical states.
• Show an example of calculations (use proper units, e.g., grams, moles, and ml where appropriate) of the following:
- Determine the molarity of NaOH through standardization.
- Determination of density of vinegar.
- Determination of acetic acid molarity in vinegar as well as mass percent.
• Results should include minimal text, any analysis should go in the Discussion.
