Question
I need net ionic equations for these two tables please.
1.a.
Table 1. Tests for Unknown Anions
Ba(NO3)2
Fe(NO3)3
Pb(NO3)2
AgNO3
G2A (Cl-) –HNO3

These are the unknowns for table 2. I need net ionic equations for them interacting with other substances
W6a- Fe3+
W6b-Na+
W6c- PB2+
Ba(NO3)2
Fe(NO3)3
Pb(NO3)2

Explanation / Answer
Ba(NO3)2 + 2Cl- ----> BaCl2 + 2NO3-
Fe(NO3)3 + 3Cl- ----> FeCl3 + 3NO3-
Pb(NO3)2 + 2Cl- ----> PbCl2 + 2NO3-
AgNO3 + Cl- ----> AgCl + NO3-
Ba(NO3)2 + CO32- ----> BaCO3 + 2NO3-
2Fe(NO3)3 + 3CO32- ----> Fe2(CO3)3 + 6NO3-
Pb(NO3)2 + CO32- ----> PbCO3 + 2NO3-
2AgNO3 + CO32- ----> (Ag)2CO3 + 2NO3-
Fe(NO3)3 has yellow colour itself, and no possible reaction takes place with NO3-
2)
Fe3+ + Na2SO4 ----> Fe2(SO4)3 + 2Na+
Fe3+ + 2Na2S2O3 ----> FeS4O6 + 4Na+
Fe3+ + 3NaI -----> FeI3 + 3Na+
Fe3+ doesn't react with ammonia to form complex ,instead the reason i can give for colour is the fpr formation of [Fe(H2O)6]3+ which is light orange/yellow
Pb2+ + Na2SO4 ----> PbSO4 + 2Na+
Pb2+ + 2Na2S2O3 ----> (No confirmed answer)
Pb2+ + 2NaI ---- PbI2 + 2Na+
Pb2+ reaction with aqueous ammonia to give Pb(OH)2 and which is not a ammonia complex ..
