Analytical applications of liquid junction potential
Abstract
Analytical applications of the liquid junction potential.
Abstract
The results presented in this thesis reveal a marked improvement
in the use of liquid junction potential which in most occasions is
a bother in our electrochemical measurement. The liquid junction
potential is encountered in many living and non-living systems. In
all concentration cells there is a component arising from liquid
junction. The concept of liquid junction is as old as the
electrochemistry and in this research we have used the liquid
junction as an analytical tool.
The main work has been to develop a convenient method of setting up
a cell that offers a straight forward liquid junction measurement.
This cell is then used to study the variation of (liquid
junction potential) with concentration and hence used this as an
analytical probe by adopting the usual calibration curve method.The
liquid junction potential was found to have a linear relationship
with concentration. This enabled the use of the plot to obtain the
concentration of unknown solution.The theoretical liquid junction
was compared with observed one and they were found to be almost the
same. An attempt was also made to make a cheaper F- responsive
electrode. The result was positive as the electrode was more
responsive towards the fluoride solutions.
