EEE 304 LAB SHEET CERTIFICATION
SCRIPT 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◍ Striker.
Answer: Used to light a Bunsen Burner
◍ in the E1 lab, amberlyst 15 is ________________ and is being used as a
_____________________.
Answer: an acidic polymer;a catalyst
◍ Electronic Balance.
Answer: An instrument to measure mass; in grams
◍ before filling the separatory funnel with liquids, you should.
Answer: rest the separatory funnel on an iron ring support, make sure that
the stopcock is closed and doesn't leak, and place a beaker under the
separate funnel
◍ Beaker.
Answer: Holds liquids; Used for heating liquids; Not a measuring device
◍ in a standard extraction, how should a separatory funnel be shaken?.
Answer: vigorously
◍ Test Tube.
Answer: Container for reactions
◍ in column chromatography, why is it important to pack the column properly,
and avoid draining the solvent below the top surface of the column?.
Answer: because air bubbles and cracks cause uneven flow and thus poorer
separation
◍ is methanol the same alcohol found in beer/wine/liquor?.
, Answer: noyour liver converts methanol first to formaldehyde and then to
formic acid. drinking methanol can cause blindness and death
◍ the reaction you will be performing requires a source of chloride ion, which
is the required nucleophile. a sodium chloride solution would be much more
safe than a HCl solution. why is acid required?.
Answer: acid protonates the hydroxyls of the starting material, turning them
into a better leaving group
◍ true or false: in general, the more polar or hydrogen-bonding a molecule, the
higher its Rf on a silica gel TLC plate.
Answer: false
◍ what is a theoretical plate?.
Answer: an evaporation/condensation cycle
◍ Glass Plate.
Answer: Used as a cover or platform
◍ Graduated Cylinder.
Answer: Used to measure volumes; in mililiters
◍ Spatula or Scoopula.
Answer: Used to transfer solids
◍ Evaporating Dish.
Answer: Used to evaporate liquids from a mixture
◍ what is the correct disposal method for a sulfuric acid mixture that remains
in the reaction vile?.
Answer: in the fume hood, pour the acid into water to dilute it. then rinse the
vial with water. dispose of the dilute acid in the aqueous waste carboy
◍ Funnel.
Answer: Liquid transfer; Separation techniques
◍ organic chemists routinely use ________ to purify multigrain quantities of
compounds, and then _____________ to test the fluent contents.
Answer: column chromatographythin-layer chromatography
