Isolating and identifying unknowns crystallized from various solvents or separated by
high performance liquid chromatography (HPLC).
Evaluating and characterizing optically active compounds by measuring their specific rotation and comparing this value with the
theoretical values found in literature.
Investigating kinetic reactions by measuring optical rotation as a
function of time.
Monitoring changes in concentration of an optically active component in a reaction mixture, as in
enzymatic cleavage.
Analyzing molecular structure by plotting ____over a wide range of wavelengths.
optical rotatory dispersion curves
Distinguishing between
optical isomers.
Branched of electrochemistry which deals with the study and measurement of electrode potentials.
POTENTIOMETRY
It is employed to find the concentration of a solute in solution
POTENTIOMETRY
It is when the pair of electrodes is placed in the sample solution it shows the potential difference by the addition of the () or by the change in the () of the ions.
titrant, concentration
is the electrode which contains of its own potential value, and it is stable when dipped into sample solution.
The reference electrode
is used to prevent the interference of the analyte solution with that of reference solution.
The salt bridge
is the electrode which responds to change in the potential of analyte solution.
The indicator electrode
The electromotive force of the complete cell is given by the following equation
Ecell = Ereference + Eindicator+ Ejunction
