Concept explainers
(a)
Interpretation:
The source of junction potential in a glass-reference electrode system should be predicted.
Concept introduction:
Glass electrode consists of a glass bulb that contains a solution of hydrochloric acid with fixed concentration. It is a type of ion selective electrode. It measures the pH of the solution.
(b)
Interpretation:
The source of boundary potential in a membrane electrode should be predicted.
Concept introduction:
Membrane electrodes consists a thin glass membrane and are used to measure the pH of the solution.
(c)
Interpretation:
The source of asymmetric potential in a glass-membrane electrode should be predicted.
Concept introduction:
Membrane electrodes consists a thin glass membrane and are used to measure the pH of the solution.
(d)
Interpretation:
The source of the potential of a crystalline membrane electrode that is used to determine the concentration of
Concept introduction:
Membrane electrodes consists a thin glass membrane and are used to measure the pH of the solution. Crystalline membrane are manufactured by the ionic compounds or a homogeneous mixture of ionic compounds.
