Question
AgNO_3 reacting with NACl: Precipitate or No Precipitate Balanced overall molecular equation: Balanced net ionic equation: AgNO_3 reacting with Cu(NO_3): Precipitate or No Precipitate Balanced overall molecular equation: Balanced net ionic equation: C. AgNO_3 reacting with Na_3PO_4: Precipitate or No Precipitate Balanced overall molecular equation: Balanced net ionic equation: D. NaCl reacting with Cu(NO_3)_2: Precipitate or No Precipitate Balanced overall molecular equation: Balanced net ionic equation:Explanation / Answer
a) Balanced Overall Molecular equation:
AgNO3 + NACL = NANO3 + AgCL
Balanced Net Ionic Equation:
AgNO3(aq) + NaCl(aq) ---> AgCl(s) + NaNO3(aq)
AgCl precipitated out of solution because it's insoluble in water. We first write the complete ionic equation before we write the net ionic equation. To write the ionic equation, we separate all the aqueous compounds into ions and leave the solid compound unseparated.
Ag+ + NO3- + Na+ + Cl- ---> AgCl(s) + Na+ + NO3-
Then, we omit the spectator ions- the ions that appear on both sides of the equation. We're left now with the net ionic equation
Ag+ + Cl- ---> AgCl(s)
Precipitation
AgCl Precipitate out of solution because it's insoluble in water.
b) Balanced Overall Molecular equation:
Cu + 2AgNO3 = Cu(NO3)2 + 2Ag
Balanced Net Ionic Equation:
it is single replacement. The nitrate will be a spectator ion (it is always soluble).
Cu + 2AgNO3 --> Cu(NO3)2 + 2Ag
complete ionic
Cu + 2Ag^+ + 2NO3^- --> Cu^2+ 2NO3^- + 2Ag
Net ionic
Cu + 2Ag^+ --> Cu^2+ 2Ag
Cu and Ag are (s)
2Ag^+ Cu^2+ are (aq)
Precipitation:
Ag (Silver) Precipitate
c) Balanced Overall Molecular equation:
3 AgNO3(aq) + Na3PO4(aq) = Ag3PO4(s) + 3 NaNO3(aq)
Balanced Net Ionic Equation:
Complete ionic equation:
2 Na+(aq) + PO43-(aq) + 3 Ag+(aq) + 3 NO3-(aq) --> 3 Na+(aq) + 3 NO3-(aq) + Ag3PO4(s)
Net ionic equation (eliminate spectator ions):
3 Ag+(aq) + PO43-(aq) --> Ag3PO4(s)
Precipitation:
Precipitation of Ag3PO4
d) Balanced Overall Molecular equation:
Cu(NO3)2(aq) + 2 NACl(aq) = CuCl2(s) + 2 NANO3(aq)
Balanced Net Ionic Equation:
Cu(NO3)2 + 2 NaCl = CuCl2 + 2 NaNO3
Net ionic
Cu2+ + 2 Cl- = CuCl2
Precipitation
Precipiate of Salt i.e NaCl
