Homework Answers
The coefficient of Bi+3 is 1 after balancing the equation completely hydrogens, oxygen atoms and the charge balancing on bothe sides.
Bi+3 + 2Fe+3 +6OH- ---------------------------> BiO3- + 2Fe+2 + 3H2O
oxidation half
Bi+3 + 6OH- ------------------> BiO3- + 3H2O + 2 e- ( oxidation state of Bi changes from +3 to +5)
reduction half
2 Fe+3 + 2e- ---------------------> 2Fe+2 ( oxidation state of Fe changes from +3 to +2)
---------------------------------------------------------------------------------------------------------------------------
Bi+3 + 2Fe+3 +6OH- ---------------------------> BiO3- + 2Fe+2 + 3H2O
------------------------------------------------------------------------------------------------------------
option a is correct
