Explanation / Answer

Q2.

balance net ionic euqations

precipitateion of Tin(IV) sulfide via H2S

Sn+4(aq) + 2H2S(aq) --> H2(g) + SnS2(s)

net ionic:

Sn+4(aq) + 4H+(aq) + 2S-2(aq) --> 2H2(g) + SnS2(s)

for

confrimation test of tin:

Sn will preciptiate with OH- in solution if left over

Confirmig test for copper --> copper can form the next complex:

2 Cu(NH3)4(NO3)2 + 10KCN + H2O --> 2K3[Cu(CN)4] + 4KNO3 + NH4CN + NH4CNO + 6NH3

whch is a unique identity test; that is, No tin will be able to precipitate
