Electrolyte A substance whose aqueous solutions conduct electricity due to ions in solution. Acids, bases, and soluble salts are electrolytes. 

A strong acid is an example of a strong electrolyte, a substance whose aqueous solutions are good conductors of electricity (T Figure 14.10). Aqueous solutions require the presence of charged particles to conduct electricity. Strong acid solutions are also strong electrolyte solutions because each acid molecule... 

A weak acid is an example of a weak electrolyte, a substance whose aqueous solutions are poor conductors of electricity ( Figure 14.12). Weak acid solutions contain few charged particles because only a small fraction of the acid molecules ionize into positive and negative ions. 

Precipitation Reactions. Exchange reactions involve ionic compounds. Some ionic compounds are soluble in water and others are not. When an ionic compound dissolves in water, it dissociates into ions when an ionic compound is completely converted to ions and forms an aqueous solution, it is referred to as a strong electrolyte. An electrolyte is a substance whose aqueous solution contains ions and conducts electricity. 

Electrolytes are defined as substances whose aqueous solutions conduct electricity due to the presence of ions in solution. Acids, soluble bases and soluble salts are electrolytes. Measuring the extent to which a substance s aqueous solution conducts electricity is how chemists determine whether it is a strong or weak electrolyte. If the solution conducts electricity well, the solute is a strong electrolyte, like the strong acid, HC1 if it conducts electricity poorly, the solute is a weak electrolyte, like the weak acid, HF. 

Many reactions, particularly those that involve ionic compounds, take place in aqueous solution. Substances whose aqueous solutions contain ions and therefore conduct electricity are called electrolytes. Ionic compounds, such as NaCl, and molecular compounds that dissociate substantially into ions when dissolved in water are strong electrolytes. Substances that dissociate to only a small extent are weak electrolytes, and substances that do not produce ions in aqueous solution are nonelectrolytes. Acids dissociate in aqueous solutions to yield an anion and a hydronium ion, H30 +. Those acids that dissociate to a large extent are strong acids those acids that dissociate to a small extent are weak acids. 

A substance (such as NaCl) whose aqueous solutions contain ions is called an electrolyte. A substance (such as C12H22O11) that does not form ions in solution is called a nonelectrolyte. The different classifications of NaCl and C12H22O11 arise largely because NaCl is ionic, whereas C12H22O11 is molecular. 

Any substance whose aqueous solution contains ions is called an electrolyte. Any substance that forms a solution containing no ions is a nonelectrolyte. Electrolytes that are present in solution entirely as ions are strong electrolytes, whereas those that are present partly as ions and partly as molecules are weak electrolytes. Ionic compounds dissociate into ions when they dissolve, and they are strong electrolytes. The solubility of ionic substances is made possible by solvation, the interaction of ions with polar solvent molecules. Most molecular compounds are nonelectrolytes, although some are weak electrolytes, and a few are strong electrolytes. When representing the ionization of a weak electrolyte in solution, half-arrows in both directions are used, indicating that the forward and reverse reactions can achieve a chemical balance called a chemical equilibrium.
