Quant Exam 3 Flashcards
charge balance
the sum of the positive charges in solution equals the sum of the negative charges in solution
T or F: The coefficient of each term in the charge balance equals the magnitude of the charge on each ion.
T
mass balance
the quantity of all species in a solution containing a particular atom must equal the amount of that atom delivered to the solution
T or F: The element with the highest electronegativity is the strongest oxidizing agent.
T
T or F: The strongest reducing agents will have the largest negative potentials.
T
What is Eo?
cell potential at standard conditions (will usually be provided)
Formula for Eo
Eo = Eo (cathode) - Eo (anode)
Setup for Simple Absorption Spectrophotometer
light source, monochromator, sample, detector
UV transition state
bond breakage, electronic
Setup for Simple Emission Spectrophotometer
light source, excitation monochromator, sample, emission monochromator, detector
microwave transition state
molecular rotation
visible transition state
electronic excitation
infrared
molecular vibration
large separation factor, want steep/narrow peaks, want a large number plates, and small plate height
longer length means better, want higher temp, thicker coating
