Question

Adding too much of one of these substances to a sample may result in overly intense readings of C-H bonds. For 10 points each:
[10h] Name these substances mixed with a ground-up sample during the preparation stage of a technique. Common examples of these substances include Fluorolobe and Nujol.
ANSWER: mulling agents [or mulls; prompt on mineral oils]
[10e] Mulls are prepared for this technique, which detects a molecule’s vibrational modes using light of longer wavelength than visible light.
ANSWER: infrared spectroscopy [or IR spectroscopy]
[10m] During IR spec, mulls are loaded onto a plate often made of this compound or potassium bromide. Neutralizing lye with hydrochloric acid produces water and this compound.
ANSWER: sodium chloride [or NaCl; accept table salt; accept salt table; accept halite; accept salting out; prompt on brine]
