SOME THEORY ABOUT pH
pH is a measurement for the acidity or alkalinity of a solution. In pure water the hydrogen ion (H+) and hydroxyl ion
(OH-) concentrations are equal at 10-7 M (25°C). To provide
a convenient and effective means of defining acidity and
alkalinity, the pH is
defined as the negative
logarithm of hydrogen
activity:
pH = -log [H+]
The heart of a pH measuring system is a membrane made from special pH-selective glass
on which a very thin
layer of hydrogen ions
is formed when dipped
in water. At high pH
values, this layer will have a low hydrogen concentration.
However, at low pH values a large number of H+ ions diffuse
in the layer. By measuring the generated electrical potential
(E) in the layer the corresponding pH can be computed.
Solution-1: sample to be measured
Solution-2: known buffer solution (7 pH)
Reference-1: silver wire in a salt-bridge (KCI)
Reference-2: silver wire in a salt-bridge (KCI)
Membrane layer-1: H+
ions generated by the
sample
Membrane layer-2: H+
ions generated by the
buffer
The potential (E) between both wires will
vary with the pH difference between sample and known buffer
according the Nernstequation: (-59.2 mV/pH
at 25°C). A salt-bridge
around each wire prevents direct metal contact with the solutions
by using a wet junction
for a stable electrical
behaviour.
Combination Electrode
A combination electrode
has an indicating and
a reference electrode
combined into a single body that is easy to use and popular
because of its compactness. A minimum amount of sample
is required due to the close proximity of the pH responsive
membrane and the liquid junction.
Junction Types
Glass combination electrodes mostly feature an anti-fouling annular ceramic junction. The annular junction is formulated with a special ceramic which encircles the glass bulb.
Numerous pores in the ceramic provide lower resistance and
more stable pH readings.
Epoxy body combination electrodes come standard with a
specially formulated porous ceramic plug junction.
Sleeve junctions provide the highest flow rate for difficult
samples.
A double junction reference is constructed with an Ag/AgCl
inner chamber and a chemically compatible reference solution in the outer chamber. It is recommended for samples
containing organic compounds, proteins, heavy metals, and
other compounds that interact with silver, such as bromides,
iodides, cyanides, and sulphides.
