Redox and Electrochemistry Water solutions of certain substances conduct an electric current ?These substances are lectrolytes It is a sustance that dissolves in water to form a solution that will conduct an electric current If it does not coduct at all?Nonelectrolytes The reason that substances vary in their ability to conduct is related to number of ions in solution Ionic lattice substances?Sodium chloride?Dissociated by water molecules so that the individual positive and negative ions are dispresed throughout the solution Covalent bond?Degree of polarity determines the extent to which it will be ionized Water molecules help waken and finally break the polar covalent bonds Ionization? When ions are formed Dissociation?Ionic lattice comes apart
