How much theory of each of these instruments do we need to know for the exam? So far Ive been focusing on just how to read and interpret the graphs and havnt been working on how much they actually work.
-
yeah .. basically read and interpret the graph...
identifying the substance under analysis ..
i think that is as far as it goes
-
For all of the three instruments, you need to be familiar with interpreting their graphs.
You need to know the instruments of IR and Mass Spec really well, because you may be asked to name some components or discuss some logic behind them.
For NMR, you need to know the concept of nuclear magnetic resonance and understand the purpose of tetramethylsilane

Do we need to know like detailed stuff about each analytical technique such as how? what is involved? the equipment

yes.

yes.
Even the explanation of the pulsed light in IR and AAS with all the mirrors and reference cells etc?
-
pulsed light defs, dunno about the mirrors and reference cells
-
id learn em just to be safe.
-
in one of the pass papers they asked for the purpose of the light and the flame and the monochromator and the dectector :P one mark each ! omg. :P

isnt that a good thing...easy marks?
-
Gosh, why is infrared spectra so weird? The absorbance decreases and the wave number decreases on the axis

i dont get it so its hard --"
-
BTW, there is no point learning what they do I don't think they are interested in that...perhaps learn the important features such as differences in colorimetry, UV, AAS, purposes of them, what they can be used for etc

Do you think it's worth memorising that grid on page 120 of the Heinemann Chemistry 2 textbook?

LOL no!

So, since there is some background knowledge that we need to retaing, what does everybody think is the ideal amount number of times to spend reading each chapter of the textbook?
-
Depends on how you "read" it. I don't read it like I do an English novel lol

Yeah I try this with my chem textbook on the train all the time and it never works, I don't learn anything. You need to make notes or do some questions to consolidate.
