Balance the following redox equations using the half-reaction method:
a) H2SEO3 + H2S → Se + HSO41-
(H*)
b) AszS3 + Ci031- → Cl1- + H2ASO41- + S
(H*)
c) P → PH3 + H2PO21-
(OH1-)
d) NO31- + BizS3 → Bi3+ + NO + S
(acidic solution)
e) Bi(OH)3 + Sn(OH)31- → Sn(OH)62- + Bi
(basic solution)
f) MnO41- + NO21- → MnO2 + NO31-
(OH2)
g) HO21- + Cr(0H)41- → CrO42- + OH1-
(basic solution)
h) Brl- + SO42- → Br2 + SO2
(H-)
i) Fe0 + H202 → Fe3+ + H20
(acidic solution)
