Much of chemistry relies upon finding out what compound you have in your sample and how pure that sample is. Chemists use a variety of methods to find out what their new substance contains.
Wet tests are chemical tests to determine your compounds contents. These are usually chemical reactions that give a clear visible sign to show that there is a specific species present.
The wet tests we will look at are for:
- Typical reaction compounds and products
- Common ions, cations and anions
- Organic chemical tests
(sometimes called dry tests) involve using instruments to measure certain properties of compounds from the absorbance of radiation & the emission spectra when heated to the paramagnetic properties or the speed at which it passes through a column or chromatogram
Common spectroscopic techniques are:
- NMR Spectroscopy
- Infra-Red Spectra
- UV-vis spectra
- Mass Spectra
- EPR spectra
Watch this space. Pages on these spectroscopic techniques will appear over the next few weeks!
