If sodium hydroxide solution were to splash in your face while you were wearing

Question

If sodium hydroxide solution were to splash in your face while you were wearing safety goggles, which do you think would be the wiser response: (a) remove your goggles, then wash your face in the eyewash fountain; or (b) wash your face while leaving the goggles on? Briefly explain. (a) 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

1. If you were wearing safety goggles and the eyes are not involved then to prevent flushing NaOH into the eye, flush the face leaving goggles on.

However, if the eyes are involved, remove goggles immediately and flush your eyes in eyewash fountain by keeping the eyelids open using your finger as prop.
