Aqueous solutions of ions conduct electricity. Compounds that dissociate into ions to a large extent (70-100%) when dissolved in water are called strong electrolytes . Most molecular compounds that dissolve in water do not dissociate into ions. These molecular compounds are called nonelectrolyte s. C 2 H 5 OH( l ) C 6 H 12 O 6 ( s ) What about acetic acid? CH 3 CO 2 H( aq ) CH 3 CO 2 ( aq ) + H + ( g ) 2
