<P> Reactions in aqueous solutions are usually metathesis reactions . Metathesis reactions are another term for double - displacement; that is, when a cation displaces to form an ionic bond with the other anion . The cation bonded with the latter anion will dissociate and bond with the other anion . </P> <P> Aqueous solutions that conduct electric current efficiently contain strong electrolytes, while ones that conduct poorly are considered to have weak electrolytes . Those strong electrolytes are substances that are completely ionized in water, whereas the weak electrolytes exhibit only a small degree of ionization in water . </P> <P> Nonelectrolytes are substances that dissolve in water yet maintain their molecular integrity (do not dissociate into ions). Examples include sugar, urea, glycerol, and methylsulfonylmethane (MSM). </P> <P> When writing the equations of aqueous reactions, it is essential to determine the precipitate . To determine the precipitate, one must consult a chart of solubility . Soluble compounds are aqueous, while insoluble compounds are the precipitate . Remember that there may not always be a precipitate . </P>
