A nonelectrolyte is a substance that dissolves to give a solution that does not conduct electricity. Nonelectrolyte solutions (solutions of nonelectrolytes) do not contain ions. Aqueous solutions of acetone (1) and glucose (2) are nonelecrrolyte solutions. 

One key property of a solution is its electrical conductivity or ability to conduct electricity. When a substance, a solute, is dissolved is water, a solvent, ions may or may not be formed. A strong electrolyte is formed when the solute completely ionizes (the substance completely separates into ions), such as sodium chloride (a soluble salt), hydrochloric acid (strong acid), or sodium hydroxide (strong base). A weak electrolyte is formed when the solute partially ionizes, such as acetic acid (weak acid) or ammonia (weak base). A nonelectrolyte is a substance that dissolves in water but does not ionize, such as sugar or alcohol. Most soluble, nonacid organic molecules are nonelectrolytes. 

Nonelectrolytes are substances that dissolve in water but do not produce any ions [see Fig. 4.4(c)]. An example of a nonelectrolyte is ethanol (see Fig. 4.3 for the structural formula). When ethanol dissolves, entire C2H5OH molecules are dispersed in the water. Since the molecules do not break up into ions, the resulting solution does not conduct an electric current. Another common nonelectrolyte is table sugar (sucrose, Ci2H220h), which is very soluble in water but produces no ions when it dissolves.

We can divide the substances that dissolve in water into two broad classes, electrolytes and nonelectrolytes. An electrolyte is a substance that dissolves in water to give an electrically conducting solution. Sodium chloride, table salt, is an example of an electrolyte. When most ionic substances dissolve in water, ions that were in fixed sites in the crystalline solid go into the surrounding aqueous solution, where they are liee to move about. The resulting solution is conducting because the moving ions form an electric current Thus, in genraal, ionic solids that dissolve in water are electrolytes. 

A nonelectrolyte is a substance that dissolves in water to give a nonconducting or very poorly conducting solution. A common example is sucrose, C12H22O11, which is ordinary table sugar. Another example is methanol, CH3OH, a compound used in car window washer solution. Both of these are molecular substances. The solution process occurs because molecules of the substance mix with molecules of water. Molecules are electrically neutral and cannot carry an electric current, so the solution is electrically nonconducting. 

By contrast, a solution containing neutral solute molecules does not conduct electric current because it does not contain mobile, charged particles. A substance that dissolves in water to give a solution that does not conduct an electric current is called a nonelecirolyte. Sugar is a nonelectrolyte. 

You have probably heard of electrolytes in the context of sports drinks such as Gatorade. Electrolytes in body fluids are necessary for the transmission of electrical impulses, which are critical to physiological processes such as nerve impulses and muscle contractions. In general, an electrolyte is a substance that dissolves in water to yield a solution that conducts electricity. By contrast, a nonelectrolyte is a substance that dissolves in water to yield a solution that does not conduct electricity. Every water-soluble substance fits into one of these two categories. 

An electrolyte is a substance that, when dissolved in a solvent or melted conducts an electrical current. A nonelectrolyte does not conduct a current when dissolved. The conduction of the electrical current is usually determined using a light bulb connected to a power source and two electrodes. The electrodes are placed in the aqueous solution or melt, and if a conducting medium is present, such as ions, the light bulb will light, indicating the substance is an electrolyte. 

A substance that can dissolve in water but results in a poorly conducting solution is called a nonelectrolyte. Glucose (CgH Og) is a nonelectrolyte. A nonelectrolyte is not charged in solution because it dissolves as molecules in water radier than ions, and thus caimot conduct electricity. 

Ions are commonly found in a class of compounds called salts, or ionic solids. Salts, when melted or dissolved in water, yield solutions that conduct electricity. A substance that conducts electricity when melted or dissolved in water is called an electrolyte. Table salt — sodium chloride — is a good example. On the other hand, when table sugar (sucrose) is dissolved in water, it becomes a solution that doesn t conduct electricity. So sucrose is a nonelectrolyte. Whether a substance is an electrolyte or a nonelectrolyte gives clues to the type of bonding in the compound. If the substance is an electrolyte, the compound is probably ionically bonded (see Chapter 6). If it s a nonelectrolyte, it s probably covalently bonded (see Chapter 7).

Whether or not an aqueous solution is a conductor of electricity depends on the nature of the solute(s). Pure water contains so few ions that it does not conduct electric current. However, some solutes produce ions in solution, thereby making the solution an electrical conductor. Solutes that provide ions when dissolved in water are called electrolytes. Solutes that that do not provide ions in water are called nonelectrolytes. All electrolytes provide ions in water but not all electrolytes are equal in their tendencies for providing ions. A strong electrolyte is a substance that is essentially completely ionized in aqueous solution essentially all of the dissolved solute exists as ions. A weak electrolyte is only partially ionized in aqueous solution only some of the dissolved solute is converted into ions. One scheme for classifying solutes is summarized in Figure 5-3. 

As mentioned before, certain covalent compounds, like alcohols, readily dissolve in water because they are polar. Since water is polar, and these covalent compounds are also polar, water will act as a solvent for them (general rule of solubility Like dissolves like ). Compounds like alcohols are nonelectrolytes—substances that do not conduct an electrical current when dissolved in water. However, certain covalent compounds, like acids, will ionize in water, that is, form ions ...
