Electrochemical Methods

Question 1

Potentiometry

Answer 1

Techniques that measure the voltage while keeping the current constant

Question 2

Indicator electrode potentiometry

Answer 2

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

Question 3

Metal electrodes

Answer 3

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

Question 4

Membrane electrode

Answer 4

Function be sensing the transfer of ions from one side of a selectively permeable membrane to the other

I.e. Glass electrode

Question 5

Potentiometric titration

Answer 5

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

Question 6

Voltametry

Answer 6

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

Question 7

Electrogravimetry

Answer 7

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

Question 8

Coulometry

Answer 8

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