Analytical chemistry Flashcards
what is analytical chemistry
Methods for determining the chemical composition of chemical components, sometimes in complex samples
what is qualitative analysis
Determine the identity of species or functional groups in the sample
what is quantitative analysis
Determine the amount of analytes present
name 4 classical wet chemical methods
precipitation
extraction
distillation
gravimetric and titrimetric measurements
name 4 instrumental analytical methods
light absorption or emission
mass-to-charge ratio
fluorescence
NMR
what is chromatography
means of separating and tentatively identifying components present in a mixture
what is spectrophotometry
study the absorption of light by chemical substances
what is spectrometry
used to measure the molecular mass of a compound
what is atomic spectroscopy
determination of elemental composition by its electromagnetic or mass spectrum
what is molecular spectroscopy
the absorption, emission and scattering of a proton when the energy of a molecule changes
what is electrochemistry
shifts in electrical current is measured from oxidation or reduction reactions
