15Solubilitykey PT: most lonic compands are solutible in water, andable to be dissolved (aq)therefore will disociate into ions (will be electrolytes)But Some are insoluable in watercan't be dissolved (s)? How do we know which ones are soluabeinsoluable?"consulte solubility Rules/Table a summary ofempirical observations regarding the solubility of ionic compountsPercipitation Reactions:(aq)Occur when two soluable reactonts are combined in aqueussolutions and a new insoluable product is formed(s)called the percipitate"NH4AgNH4+Ag+NO2C1,C1(NO3)NM4C1 (aq) AgNO3(aa)Possil ble products? must be new from partner swapping/doubledisplacement.NHyNO3(aq)AgCI (5) percipitateYou need to write 3 types of chemical equations for percipitationreactions.ICM: NH4Cl (aq) + Ag NO3 (aq)AgCI(s) +NH4NO3(aq),(complete molecular)1) x Evergone gets a phase label2) check and make sure you balance'it27 2CI:(complete lonic)seperate all ag species into ions (need charges)NH4+ (aq) + CF (aq)+ (s) + NH4+ (aeN03-caq)"LOOK for spectator ions" (NH4+ (ag), N03(aq)same on both sides3NI(net ionic)remove the spectator ionsshow the formation of thepercipitate,(Ag*(aq)+C1-(aq)- Agci(s)
