Web-either of the above When some substances (electrolytes) are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. If the physical or chemical process that generates the ions is essentially 100% efficient (all of the dissolved compound yields ions), then the substance is known as a strong electrolyte. WebIonic Electrolytes. Water and other polar molecules are attracted to ions, as shown in Figure 2. The electrostatic attraction between an ion and a molecule with a dipole is called an ion-dipole attraction. These attractions play an important role in the dissolution of ionic compounds in water.
