Circuitry, electrode configuration and calibration procedures are described for a conductance device. An alternative construction of the circuit is given allowing computer capture of the instrument response. A correlation is displayed between conductance (mho) measured by the device with a fixed electrode configuration and the response of a commercial conductivity meter (mho/cm). The correlation is established for aqueous solutions exhibiting conductivities in a three orders of magnitude range. Conductance measurements are listed for a homologous series of alcohols.

Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
