Explain the differences in conductivity of NaCl, {eq}CaCl_2 {/eq}, and {eq}AlCl_3 {/eq}.

Question:

Explain the differences in conductivity of NaCl, {eq}CaCl_2 {/eq}, and {eq}AlCl_3 {/eq}.

Electrical Conductivity:

An electrolyte is a solution that is capable of conducting electricity. It contains mobile (free) ions that are capable of moving between the electrodes carrying electrical charges. Most ionic solids, when dissolved in water, form electrolytes. Covalent molecules generally do not conduct electricity.
