Lab-Aids: Conductivity of Solutions Experiment Kit
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 indicators are required for these activities but are not included. We recommend the LAB-AIDS‚® Conductivity Indicator. This kit is packaged for use with 30 students.
