#### Solution Preview

Could you please tell me the name of the following solutions after they are mixed and what their net ionic equations would be?
Please see Guide at the end, too...
-ammonia poured into aluminum nitrate
NH3(aq) + H2O ---> NH4+(aq) + OH-(aq)

Al(NO3)3 + 3 OH-(aq) ----> Al(OH)3(s) + 3 NO3-(aq)

Al3+(aq) + 3 OH- ----> Al(OH)3(s) (aluminum hydroxide)

-barium chloride poured into sodium sulfate
BaCl2(aq) + Na2SO4(aq) ----> BaSO4(s) + 2 NaCl(aq)

"Insides" combine and "outsides" combine

"Insides" = Na+ and Cl- ---> NaCl(aq)
"Outsides" = Ba2+ and SO42- ----> BaSO4(s)

The net ionic equation is the one that gives the solid (barium sulfate = BaSO4)...please see the solubility chart in the guide I attached to the end.

Ba2+(aq) + SO42-(aq) ----> BaSO4(s)

-copper(II) chloride poured into sodium carbonate

CuCl2(aq) + Na2CO3(aq) ----> CuCO3(s) + 2 NaCl(aq)

"Insides" combine and "outsides" combine

"Insides" = Na+ and Cl- ---> NaCl(aq)
"Outsides" = Cu2+ and CO32- ----> CuCO3(s)

The net ionic equation is the one that gives the solid (copper (II) carbonate = CuCO3)...please see the solubility chart in the guide I attached to the end.

Cu2+(aq) + CO32-(aq) ----> CuCO3(s)

-lead(II) nitrate poured into potassium iodide

Pb(NO3)2 (aq) + 2 KI(aq) ----> PbI2(s) + 2 KNO3(aq)

"Insides" combine and "outsides" combine

"Insides" = K+ and NO3- ---> KNO3(aq)
"Outsides" = Pb2+ and I- ----> PbI2(s)

The net ionic equation is the one that gives the solid (lead (II) iodidePbI2)...please see the solubility chart in the guide I attached to the end.

Pb2+(aq) + 2 I-(aq) ----> PbI2(s)

-mercury(II) chloride poured into potassium iodide

HgCl2 (aq) + 2 KI(aq) ----> HgI2(s) + 2 KCl(aq)

"Insides" combine and "outsides" combine

"Insides" = K+ and Cl- ---> KCl(aq)
"Outsides" = Hg2+ and I- ----> HgI2(s)

The net ionic equation is the one that gives the solid (mercury (II) iodide = HgI2)...please see the solubility chart in the guide I attached to the end.

Hg2+(aq) + 2 I-(aq) ----> HgI2(s)

-mercury(II) chloride poured into sodium carbonate

HgCl2(aq) + Na2CO3(aq) ----> HgCO3(s) + 2 NaCl(aq)

"Insides" combine and "outsides" combine

"Insides" = Na+ and Cl- ---> NaCl(aq)
"Outsides" = Hg2+ and CO32- ----> HgCO3(s)

The net ionic equation is the one that gives the solid (mercury (II) carbonate = HgCO3)...please see the solubility chart in the guide ...
