1
Q

Potentiometry

A

Techniques that measure the voltage while keeping the current constant

2
Q

Indicator electrode potentiometry

A

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

3
Q

Metal electrodes

A

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

4
Q

Membrane electrode

A

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

I.e. Glass electrode

5
Q

Potentiometric titration

A

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

6
Q

Voltametry

A

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

7
Q

Electrogravimetry

A

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

8
Q

Coulometry

A

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