Conductivity of Solutions Experiment
kit #313
Using LAB-AIDS® Conductivity Indicators, students study the principles of ionization by differentiating between strong electrolytes, weak electrolytes and non-electrolytes. They also learn to differentiate between strong and weak acids and strong and weak bases. Performing a series of fun activities, students observe and discover dramatic results which lead to a better understanding of the principles of ionization. This Lab-Aid is designed for use by students in introductory chemistry courses and higher. Conductivity testers are required for these activities but are not included. We recommend the Lab-Aids® 9-Level Conductivity Indicator (Product ID 300M-U). This kit is packaged for use with 30 students.
