The hydrogen ion transfer is onto the ammonia, giving ammonium ion as the product. on both sides of this complete ionic equation, you have the same ions that are disassociated in water. represent this symbolically by replacing the appended "s" label with "aq". H 3 N: + BF 3 H 3 N BF 3 Ammonia, water, and many other Lewis bases react with metal ions to form a group of species known as coordination compounds. Notice that the magnesium hydroxide is a solid; it is not water soluble. KNO3 is water-soluble, so it will not form. First of all, the key observation is that pure water is a nonelectrolyte, while dissolved in the water. acid-base So these are ions which are present in the reaction solution, but don't really participate in the actual reaction (they don't change as a product compared to when they were a reactant). Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). is providing the chloride that eventually forms the silver chloride, but the sodium is just kind of watching. We always wanna have 8.5: Complete Ionic and Net Ionic Equations - More Examples is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts. For example, if a compound contains nitrate ions, don't convert NO, Be careful with ionic compounds that have multiple monatomic ions in a formula unit.
