Electrolytes are substances that dissolve in water to yield ions. They can be divided into acids, bases, and salts, because they all give ions when dissolved in water/Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes). These solutions conduct electricity due to the mobility of the positive and negative ions, which are called cations and anions, respectively/Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes). Strong electrolytes completely ionize when dissolved, and no neutral molecules are formed in solution/Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes). Small fractions of weak electrolytes molecules ionize when dissolved in water. Some neutral molecules are present in their solutions/Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes). Examples of electrolytes include acids, bases, and salts/Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes). Electrolytes are important in the human body because they conduct electricity, exert osmotic pressure, and resist pH changes in body fluids. The primary electrolytes required in the body fluid are cations (of calcium, potassium, sodium, and magnesium) and anions (of chloride, carbonates, aminoacetates, phosphates, and iodide) /Chemical_Reactions/Chemical_Reactions_Examples/Electrolytes).
