We are building a good relationship with Heinz Foods. They’re counting on us for quick,

I suggest that you titrate the vinegar. You have standardized NaOH to use for titration.
Before you start, give me the following items to review.
detailed one-page plan for the procedure with all necessary data tables
Get started in the lab as soon as our plan has been approve. When you’re finished,

5 pts mind? Example: A person can tell the difference between the waters by
observation like clarity, but all the waters had a different odor. Therefore, my
hypothesis was not correct all water is not the same by clarity. Discuss Data!
o Then, you should list at least one source of error (chemistry has more than one),
5 pts something which affected your experiment but was not in your control (called
inherent error) or which wasn’t properly controlled for, Example: change in drop
size. Discuss Data
