Strong electrolytes are good conductors of electricity, but only in aqueous solutions or in molten form. The non-ideality of electrolytic solutions is also reflected in their colligative properties, especially freezing-point depression and osmotic pressure. . The substances which ionize up to a small extent into ions are called weak electrolytes. It is of course impossible to measure the conductance of an electrolyte at vanishingly small concentrations (not to mention zero! Glycerol, C3H8O3, is a nonelectrolyte; ammonia, NH3, is a weak electrolyte; and iron (III) sulfate, Fe2 (SO4)3, is a strong electrolyte. This process of dissociation of a substance into its ions is known as ionization and the substances that undergo ionization are called electrolytes. The quantitative treatment of these effects was first worked out by P. Debye and W. Huckel in the early 1920's, and was improved upon by Ostwald a few years later. The two types of ions move in opposite directions. Thus dissociation can be seen as an acid (HA) in equilibrium with a proton (H+) and the corresponding conjugate base (A). Unauthorized use of these marks is strictly prohibited. Examples: lemon juice (2.3), and vinegar (2.9) pH 3 Concentration: 10,000.
