Post-Lab Questione Pre-Lab Questions LAB ACTIVITY Date 1 The four ionic compounds you will be given in this lab are silver nitrate, sodium chloride, copper0l) nitrate, and sodium phosphate. Using your knowledge of precipitation reactions, predict which combinations of two ionic compounds will create a precipitate. Circle either Precipitate or No Precipitate to indicate your prediction. For al of your predicted precipitation reactions, write a balanced overall molecular equation and a balanced net ionic equation. AgNO, reacting with NaCi:Precipitate pr No Precipitate Balanced overall molecular equation Cl Balanced net ionic equation: AgNO, reacting with Cu(NO): Precipitate or No Balanced overall molecular equation Balanced net ionic equation: AgNO, reacting with Na,PO Precipitate or No Precipitate Balanced overall molecular equation Balanced net ionic equation: NaCI reacting with Cu(NO) Precipitate or No Precipitate Balanced overall molecular equation: Balanced net ionic equationExplanation / Answer
AgNO3(aq)+NaCl(aq)=AgCl(s)+NaNO3(aq)
Precipitation occures
Net equation:
Ag+(aq) + Cl-(aq) = AgCl(s)
AgNO3 (aq) +Cu(NO3 )2 (aq) = Ag(NO3) (aq)+ Cu(NO3)2(aq)
No precipitation will occurs
Net :
Ag+(aq) + Cu+2(aq) + NO3-(aq) = Ag(NO3) (aq) + Cu(NO3)2(aq)
3 AgNO3(aq) + Na3PO4(aq) = 3NaNO3(aq) + Ag3PO4(aq)
Precipitation occures
Net :
Ag+(aq) + PO4-3 (aq)= Ag3(PO4)2(s)
NaCl(aq) + Cu(NO3)2(aq) = CuCl2 (aq) + NaNO3(aq)
No precipitation
Net:
Na+(aq) + Cl-(aq)+ Cu+2(aq) + NO3-(aq)= Na(NO3)(aq) + CuCl2(aq)
