Preferred Label : bulk concentration;
Detailed label : bulk concentration in electroanalysis;
IUPAC definition : In any technique that involves the establishment of a concentration gradient, either
within the material from which an electrode is made or in the solution that is in
contact with an electrode, the bulk concentration of a substance strong B /strong
is the total or analytical concentration of strong B /strong at points so remote
from the electrode-solution interface that the concentration gradient for strong
B /strong is indistinguishable from zero at the instant under consideration. In common
practice the bulk concentration of strong B /strong is taken to be the total or
analytical concentration of strong B /strong that would be present throughout the
electrode or solution if there were no current flowing through the cell and if the
electrode and solution did not interact in any way. In the absence of any homogeneous
reaction or other process that produces or consumes strong B /strong , the bulk concentration
of strong B /strong is the total or analytical concentration of strong B /strong
that is present before the excitation signal is applied.;
