Electrochemical Methods

Techniques that measure the voltage while keeping the current constant

Uses and the indicator electrode, the ion-selective electrode, that measures Jon activity directly when interested in an analyte solution, and is selectively sensitive to the element being determined

Function by sending the transfer of electrons at the interface between electrode and solution

Function be sensing the transfer of ions from one side of a selectively permeable membrane to the other I.e. Glass electrode

Uses electrodes, which can be either highly selective or universal, as indicators for determining the end points of titrations Potential vs. amount of torrent added

Techniques in which electrolysis is carried out so that the analyze is completely oxidized(or reduced) to a product of known composition

A potential ensures that continual electrolysis is applied across a weighed electrode. at the end the electrode is weighed. Deposited on working electrode

Measures the quantity of electricity required for the quantitative electrolysis of an analyte. Measure quantity of electricity consumed
