Document Summary

The purpose of the solution conductivity lab was to investigate electrical conductance of different aqueous solutions, and to relate their behavior in solution to the bonding structure of said substance. The results from the solution conductivity lab clearly indicate that a difference in bonding structure does relate to conductivity. Based on the number of ions a solution contains affects how electrically conductive a solution is affected. Similarly substances that dissolve in water to form an electrically conductive solution are electrolytes. There are strong electrolytes (all molecules dissociate to form ionic products and solution becomes strongly conductive), weak electrolytes (only a fraction of molecules dissociate), and nonelectrolytes (substances that dissolve to form nonconducting solutions). Of the 10 aqueous 0. 010 m solutions that were tested, four were found to be strong electrolytes (hcl, naoh, cu so 4 nonelectrolytes (sucrose and methanol), and four were found to be weak electrolytes (n.
