Instrumental Analysis Exam 1 Review
Questions and Answers 100% Correct
Propagation of Error - ANSWER-The square root of the sum of squares of the
measurements used to calculate your answer.
Standard Deviation - ANSWER-Propagation of Error * Mean
Example of a Morse Potential Energy Curve that Transitions in the UV range -
ANSWER-An arrow pointing from a lower level on curve E1 to a higher level on curve
E2 which is above E1.
Example of a Morse Potential Energy Curve that doesn't Transition - ANSWER-An
arrow pointing from a lower level on curve E1 to space to the left of curve E2 which is
above E1 and farther to the right of it.
Example of a Morse Potential Energy Curve that Fluoresces in the UV Range -
ANSWER-An arrow pointing from a lower level on curve E1 to a much higher level on
curve E2 which is above E1, as well as other arrows pointing from the lowest level of E2
to upper levels of E1.
Why do keep the caps on vials when weighing them? - ANSWER-To prevent
evaporation affecting mass.
Who produces the best solvents? - ANSWER-ACS
Example of a Morse Potential Energy Curve that Transitions in the IR range -
ANSWER-An arrow pointing from a lower level on curve E1 to a higher level on curve
E1.
Components of the UV-Vis Machine - ANSWER-Light Source, Wavelength Selector,
Sample, Detector, Computer
d-Oribtal Splitting - ANSWER-Based off the oxidation state of the metal (e.g. A Cr³⁺
metal would have a d³ splitting state)
Best situation to use a volumetric flask - ANSWER-Making solutions
Best situation to use a volumetric pippette - ANSWER-Delivering volume
Example of a Morse Potential Energy Curve that Transitions causes Dissociation -
ANSWER-An arrow pointing from a lower level on Curve E1 to the highest theoretical
level of E2.
