MODULE 5- Analytical Techniques
➢Analytical chemistry is a branch of chemistry that deals w
separation, identification and quantification of chemical compou
➢It involves both qualitative and quantitative analysis which is
into Classical and Instrumental analysis.
Classical- Chemical Methods which involves separations s
precipitation, extraction, distillation. It is achieved by measure
weight (gravimetrically) or volume (volumetrically).
Instrumental- Physical methods which uses advanced instrumen
results in accurate measurement without destruction of the samp
,Instrumental Analysis are further classified into two categ
Electroanalytical Techniques
Potentiometry
Conductometry
Spectro analytical Techniques
Colorimetry
, Potentiometry
➢It is one of the methods of electroanalytical chemistry w
usually employed to find the concentration of a solute in solu
➢It is based on measurement of EMF of electrochemical c
respect to change in concentration of the analyte solution.
➢Change in EMF is due to change in electrode potential of on
electrodes in a cell whose potential is dependent
concentration of the solution.
