644 CONDUCTIVITY OF SOLUTIONS
www.usp.orgadditional background information, see Theory and Practice of Electrical Conductivity Measurements of Solutions á1644ñ.] Conductivity is the measurement of the ability of a fluid to conduct electricity via its chemical ions. The ability of any ion to electrically conduct is directly related to its ion mobility.

TYPES OF SOLUTIONS
mymission.lamission.eduSolutions containing ions are conductors of electricity and those that contain molecules are non-conductors. Substances that dissolve in water to form ions are called electrolytes. The ions formed from these substances conduct electric current in solution, and can be tested using a conductivity apparatus (diagram below).
