Analytical chemistry (from the Latin: Ana = from the bottom up, lysis = break up, destroy) and is part of the chemical which aims to study the composition chemistry of a material or sample, using different methods.
methods employing chemical analysis may include:
Chemical Methods (based on chemical reactions) or classic:
titration
gravimetric analysis
Physicochemical methods (based on physical interactions) or instrumental:
spectrometric methods
electroanalytical methods
chromatographic methods Chemical methods have
Traditionally used as instruments do not require very complex (just pipettes, burettes , flasks, scales etc.) physicochemical methods, however, intrumental require more sophisticated equipment such as chromatography , crystallography, etc. .
The study of chemical methods is based on the chemical balance, which may be of the following types:
acid-base
redox balance
solubility equilibrium
complex balance
