Bases are less common as foods, but they are nonetheless present in many household products. For example, NH3 is the base, and NH4+ is the conjugate acid (the ionic form), so there is no involvement of hydroxide ions (those occur in strong bases, e.g. pH = -log (1.5) = -0.18. BA is an ionic bond, not observed in aqueous solution. NH4NO3 is the conjugate acid of the weak base ammonium hydroxide (NH4OH) and the strong acid nitric acid (HNO3). {/eq}.
