partial fraction partial fraction partial fraction Tonic and Covlent Name Dat Section OBSERVATIONS AND DATA 1. Electrolytes and Nonelectrolytes A. Record the conductivity measurement of each substance and solution tested. Then, after noting the range of measurements made (about five orders of magnitude), classify the substances and solutions as containing essentially no ions (lowest values), a few ions (middle values), or ions (highest values).
