Fe2(SO4)3 (aq) + H2SO4 (aq/l) ------> (no reaction)
2Fe(3+) + SO3(2-) + H2O ------> 2Fe(2+) + SO4(2-) + 2H(+) (probably)
Fe2(SO4)3 (aq) + H2SO4 + KMnO4 ------> (no reaction)

FeSO4(aq) + 2NaOH ------> Na2SO4 + Fe(OH)2 (s)
FeSO4(aq) + H2SO4 ------> (no reaction, probably)
FeSO4(aq) + Na2SO3 ------> (no reaction)
5Fe(2+) + 8H(+) + MnO4(-) ------> 5Fe(3+) + 4H2O + Mn(2+)

KBr + NaOH ------> (no reaction)
KBr + H2SO4 (l) ------> KHSO4 (s) + HBr (g)
[ 2HBr + H2SO4 ------> Br2 + SO2 + 2H2O ]
KBr + Na2SO3 ------> (no reaction)
10Br(-) + 16H(+) + 2MnO4(-) ------> 2Mn(2+) + 8H2O + 5Br2

3I2 + 6NaOH (aq, hot, conc.) ------> NaIO3 + 5NaI + 3H2O
I2 + H2SO4 ------> (no reaction)
I2 + SO3(2-) + H2O ------> 2I(-) + SO4(2-) + 2H(+) (probably)

Na2CO3 + Na2SO3 -------> (no reaction)
Na2CO3 + H2SO4 + KMnO4 ------> (same as one with sulphuric acid alone; KMnO4 doesn't participate in reaction.)
