79. Ionic Double Displacement Reactions: Net Ionic Reaction Equations

In this video, we discuss ionic double displacement reaction equations. Ionic double displacement reactions serve as an excellent introduction to net ionic reaction equations. Ionic double displacement reactions involve the reaction between two ionic compounds in an aqueous environment. Essentially, the cation of one ionic compound pairs with the anion of another ionic compound and vice versa. If a reaction occurs, the product is often a precipitate (a solid deposit). Solubility rules can be used to predict the formation of an insoluble ionic compound (the precipitate). A balanced ionic double displacement reaction equation in neutral formula reaction equation form shows the reactants and products as formula units with aqueous or solid phase tags. The complete ionic reaction equation shows those ionic compounds with aqueous phase tags dissociated into their constitute ions. The net ionic reaction equation shows only the ions and solid involved in the chemical reaction with spectator ions (those not involved in the reaction) removed. 00:00 Ionic double displacement reaction equations 08:30 Neutral formula reaction equation 08:48 Complete ionic reaction equation 10:07 Net ionic reaction equation 11:40 Example: silver nitrate with sodium phosphate in aqueous solution 15:52 Example: barium chloride plus sodium sulfate in aqueous solution 20:42 Example: Is there a reaction between potassium sulfate and lead(II) nitrate? 24:31 Example: Determine net ionic reaction equation for potassium sulfate with lead(II) nitrate 26:40 Application: lead pipes and drinking water
