Unformatted text preview: solution formed at the instant water solutions of two ionic compounds are mixed (before the reaction takes place). Describe the reaction that takes place in this mixture. Describe the final mixture. Write the complete equation for the reaction. Solution of Ca(NO3)2 Solution of Ca(NO3)2 and Na2CO3 at the time of mixing, before the reaction Product Mixture for the reaction of Ca(NO3)2 and Na2CO3 Complete Ionic Equation Spectator Ions • Ions that are important for delivering other ions into solution but that are not actively involved in the reaction are called spectator ions. • Spectator ions can be recognized because they are separate and surrounded by water molecules both before and after the reaction. Net Ionic Equations • An equation written without spectator ions is called a net ionic equation. Ca2+(aq) + CO32−(aq) → CaCO3(s) Writing Precipi...
