WebThe importance of potentiometry in analytical chemistry is to determine the concentration of a solute in a solution. The pharmaceutical industry uses it as a weight percentage assay for small molecule active pharmaceutical ingredients, intermediates, and raw materials. We can also use it to determine the potential of the sample solution ... WebPotentiometry is a way of measuring the electrical potential of an electrochemical cell under static conditions (i.e. no current flow). For a general reduction or oxidation (redox) reaction, the standard potential is related to the concentration of …
WebIn voltammetry, a plot of potential versus current is followed and the resulting curve is called as voltammogram. Analytical, kinetic, thermodynamic, chemical (adsorption or diffusion) … Web1 Feb 2012 · The protonation‐deprotonation equilibrium of 6‐benzylaminopurine (6‐BAP) and its derivatives was studied by potentiometry and voltammetry.
