So let's look at the reaction of Ammonia and water. So in ammonia, we have an extra pair of electrons. And in fact, this pair of electrons will take away an H ion from the water molecule and this will produce Ammonium and hydroxide. So by definition, because this guy has an extra pair of electrons, a lone pair of electrons, it acts as a bronzedidlower base. Now, a Bronzedidloric acid, are those molecules that can donate a Hydride ion. So, for example, let's look at the reaction of nitric acid and water.
