Which statement(s) is/are NOT true for an ion-selective electrode with an organic polymer membrane specific to aqueous ions? I. Two reference electrodes on either side of the organic polymer membrane of the ion- selective electrode measure the potential difference across the membrane. II. The organic polymer membrane of the ion-selective electrode separates the inner solution from the outer analyte solution. III. The organic polymer membrane of the ion-selective electrode is hydrophobic and is impregnated with a viscous organic solution containing an ion exchanger and sometimes a ligand specific for the analyte ion. IV. The potential difference across the organic polymer membrane of the ion-selective electrode occurs when the analyte ions embedded in the membrane diffuse into the inner aqueous solution, creating a junction potential.

Transcribed Image Text:Which statement(s) is/are NOT true for an ion-selective electrode with an organic polymer
membrane specific to aqueous ions?
I. Two reference electrodes on either side of the organic polymer membrane of the ion-
selective electrode measure the potential difference across the membrane.
II. The organic polymer membrane of the ion-selective electrode separates the inner solution
from the outer analyte solution.
III. The organic polymer membrane of the ion-selective electrode is hydrophobic and is
impregnated with a viscous organic solution containing an ion exchanger and sometimes a
ligand specific for the analyte ion.
IV. The potential difference across the organic polymer membrane of the ion-selective electrode
occurs when the analyte ions embedded in the membrane diffuse into the inner aqueous
solution, creating a junction potential.
V. The potential difference across the organic polymer membrane of the ion-selective electrode
is dependent only on the activity of analyte ion in the outer solution.
