Conductivity
Conductivity is a parameter used to
measure the ionic concentration and
activity of a solution. The more salt,
acid or alkali in a solution, the greater
its conductivity. The unit of conductivity is S/m, often also S/cm. The scale for
aqueous solutions begins with pure
water at a conductivity of 0.05 µS/cm
(77 °F / 25°C). Naturally occurring
waters such as drinking water or surface
water have a conductivity in the range
100 – 1000 µS/cm. At the upper end of
the chart some acids and alcalines can
be found.

Conductivity measurements are used
for applications such as in the production of ultrapure water or determining
the salinity of sea water.
Industrial process water
Concentrated acids and bases
Conductivity is measured by making a measurement of the electrical resistance.
The simplest kind of measuring cell used consists of two similar electrodes. An
alternating voltage applied to one of the electrodes causes the ions in the solution
to migrate towards the electrodes. The more ions in the solution, the greater the
current which flows between the electrodes. The instrument measures the current
and uses Ohm's law to calculate first the conductance of the solution and then –
by taken the cell data into account – the conductivity.
