Conductivity of Solutions and Principles of Ionization
This kit provides students with a hands-on experience in the principles of ionization. Using conductivity testers*, students first differentiate among strong electrolytes, weak electrolytes, and non-electrolytes. They then differentiate between strong and weak acids and strong and weak bases. This activity is designed for use by students in introductory chemistry courses and higher.
*Conductivity testers are not included with this kit. We recommend using either the Lab-Aids® 9-Level Conductivity Indicator (Product ID 300M-U) or the Lab-Aids® Audible Conductivity Indicator (Product ID CO-002).
