Write the complete ionic equation for each reaction that produced a precipitate?

Question

Write the complete ionic equation for each reaction that produced a precipitate? Write the net ionic equation for each reaction that produced a precipitate? Pb(No3)2 + NaCl= ppt Insoluble, Pb(No3)2 +NaOH= with ppt soluble, Pb(No3)2+Na2C2O4=ppt insoluble, Pb(No3)2+Al2(SO4)3=ppt insoluble, Al2(SO4)3+NaOH=with ppt soluble, Al2(SO4)3+Na2C2O4=with ppt insoluble

Explanation / Answer

1) Pb2+ 2NO3- + 2Na+ 2Cl- ---> PbCl2(ppt) + 2 Na + 2NO3- all ion in aqua state net eq Pb2+ + 2Cl- ---> PbCl2(ppt) 2) Pb2+ 2NO3- + 2Na + 2OH- -> Pb(OH)2(ppt) + 2 Na + 2NO3- net eq Pb2+ + 2OH- ---> Pb(OH)2 3) Pb2+ 2NO3- + 2Na+ C2O4 2- ---> Pb(C2O4)(ppt) + 2Na+ + 2NO3- net eq Pb2+ + C2O4 2- ---> PB(C2O4)(ppt) 4) 3Pb2+ + 6NO3- + 2Al3+ 3SO4 2- --->3 Pb(SO4)(ppt) + 2Al3+ + 6NO3- net eq Pb2+ + SO4 -2 ---> Pb(SO4) ppt 5) 2Al3+ + 3SO4 2- + 6Na + 6OH- --> 2Al(OH)3(ppt) + 6 Na+ + 3SO4 2- net eq Al3+ + 3OH- --> Al(OH)3 6) 2Al3+ + 3SO4 2- + 6Na + 3C2O42- ---> Al2(C2O4)3 (ppt)+ 6 Na+ + 3SO42- net eq 2Al3+ +3 C2O4 2- --> Al2(C2O4)3 ppt
