Question

This experiment uses the analytical technique of titration to determine the concentration of acetic acid in a vinegar sample. Find information in your textbook, a laboratory manual, or a Web site about titration procedures. Cite the sources of this information by listing the author or editor, book title, publisher, city of publication, publication date, and page number, for references in print, or the URL, for those on the Web. (b) Sketch the apparatus required for performing a titration. (c) In this experiment you will use phenolphthalein to signal the end point of your titration. What is a titration end point? How does phenolphthalein make the end point visible? Cite reference. (d) If you add phenolphthalein to a vinegar sample, what will be the color of the resulting solution? If you add phenolphthalein to a sodium hydroxide solution, what will be the color of the resulting solution? Cite reference.

Explanation / Answer

b)

c)Phenolphtalein is colorless in acidic solution and pink in basic solution.By adding the sodium hydroxide, which is a basic solution, to the acetic acid with phenolphthalein indicator, which is an acidic solution ,then at the end point a pink color is formed.
