A student carefully mixes two clear liquids in a beaker. The
student then observes the beaker for 60 seconds, watching
for signs of a chemical reaction. As she waits, she notices that
some of the chemicals have splashed onto her hand. She goes
to the paper towel dispenser and wipes her hand clean, then
returns to her observations. After careful observation, the
student concludes that no chemical reaction has taken place.
Which of the following would have been the best safety
