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 , and H 3O 4 ), two were found to be
nonelectrolytes (Sucrose and Methanol), and four were found to be weak electrolytes (N
, Urea, Sodium Acetate, and Citric Acid).
These results show that boding structures do
