Title: Redox reactions
Post by: betuqua on July 05, 2015, 09:10:24 AM

Hi, I need help to solve these redox reactions  :'(
 1. As2S3 + HNO3 -----> H3AsO4 + S + NO2 + H2O
 2. C6H5NO2 + Fe + HCl = C6H5NH3 + FeCl2 + H2O
 3. K2Cr2O7 + H2SO4 + C2H5OH = Cr2(SO4)3 + K2SO4 + CH3COOH + H20
 4. OsO4 + HCl + KCl = K2(OsCl4O2) + Cl2 + H2O
 5. NH4UF5 + F2 = UF6 + N2 + HF
 6. NaSCN + KMnO4 + H2SO4 = K2SO4 + MnSO4 + HCN + H2O + Na2SO4

Thank you very much  :)

C6H5NO2 + Fe + HCl = C6H5NH3 + FeCl2 + H2O
Check formula
