This is a simulation of a hand-held conductivity meter. A menu allows selection of a cation/anion pair, a concentration, and temperature (15-45 ?C) for measurement of conductivity. A brief discussion covers definitions of specific, molar, and equivalent conductivity and introduces the concept of ionic mobilities. A basic experiment is provided for comparing the mobilities of various cations and anions at the same equivalent concentration. An advanced experiment investigates determinations of solubility by conductivity measurements, and the determination of ionization constants of ammonia and acetic acid. Printable data sheets are provided.
