Answer #1

H3AsO3 + I3 = H3AsO4 + I-

Split

H3AsO3 --> H3AsO4

I3 = I-

balance elements

H3AsO3 --> H3AsO4

I3 = 3I-

balnce O adding H2O

H2O + H3AsO3 --> H3AsO4

I3 = 3I-

blaance H adding H+

H2O + H3AsO3 --> H3AsO4 +2H+

I3 = 3I-

balance charges

H2O + H3AsO3 --> H3AsO4 +2H+ +2e-

3e- + I3 = 3I-

Balance E

3H2O + 3H3AsO3 --> 3H3AsO4 +6H+ +6e-

6e- + 2I3 = 6I-

add both

3H2O + 3H3AsO3 + 6e- + 2I3--> 3H3AsO4 +6H+ +6e- + 6I-

cancel common terms

3H2O + 3H3AsO3 + 2I3--> 3H3AsO4 +6H+ 6I-
