They just test things, like run AAS/Fluorescence Spec/X-ray crystallography all the time. It really does sound boring as hell.Wait what is an analytical chemist? It sounds so boring whatever it is
Ohhh ok ahahha i know rightThey just test things, like run AAS/Fluorescence Spec/X-ray crystallography all the time. It really does sound boring as hell.
Hahaha half the stuff was on haberI'm not sure, however what they were looking for was stuff like Haber and Bosch
As in collaboration between Haber and Bosch.Hahaha half the stuff was on haber
_/_/_
Omg who is this bosch?!As in collaboration between Haber and Bosch.
Haber produced ammonia
Bosch produced it on an industrial scale etc etc

^^^. Bosch is not syllabusOmg who is this bosch?!
But like how do we know we're meant to talk about bosh in the question? Wot even~^^^

Well thanks fais for telling usBut like how do we know we're meant to talk about bosh in the question? Wot even~
Describe how atomic absorption spectroscopy is used to detect concentrations of metal ions in solution. (4 marks)
I changed it bit to get all marks- Sample of the solution is aspirated into the flame within the Atomic Absorption Spectrometer.
- A sample of the substance being tested for is excited in a hallow cathode lamp to emit a specific wavelength that will be absorbed by the ion if it is present in the solution. Can detect very small conc in ppm
- The light which passes through the atomized sample from nebulizer passes through a monochromator to isolate the wavelength of light that will be absorbed by the ion being tested for (diffraction grating), which is then detected by a detector (uh, should probably phrase that a bit better)
- Absorption is compared to a calibration curve from standard solutions to determine ion concentration. Absorbance is prop to conc.
If thats all you saw. You havent seen much changes at all.Sample of the solution is aspirated into the flame within the Atomic Absorption Spectrometer.

Can't we detect to ppb now?
Edit: just saw the diffraction grating part, the diffraction grating is in the monochromator (or not, prisms can also be used).
Any other opinions on the interpretation of that graph?Looks to me like they have increased the amount of all of the gasses. Then, the first and third lines (top from bottom), decrease in concentration perhaps because they were both on the same side of the equation and that side had a higher number of moles, so LCP dictates that the equilibrium should shift to favour the other side, which is corroborated by the fact that the middle line increases in concentration.
Thanks. So that's enough ifo we need to know about him right? We can bs the rest?C/Karl Bosch is the guy who developed the necessary machinery and equipment to produce ammonia on a large scale
It's a little hard because you didn't bold the changes. I saw the ppm thing, the diffraction grating and 'absorbance proportional to concentration' (I agree I needed to put in the last thing, I get in shit all the time for taking things as assumed knowledge where I shouldn't)If thats all you saw. You havent seen much changes at all.
