Question

Please help me with balancing redox reactions

Answer 1

\[I_{2}+IO_{3}^{-}+Cl^{-} \rightarrow ICl_{2}^{-} (Basic)\]

Answer 2

Redox reactions: Half-cell method

1a. Assign oxidation states/numbers
2a. Separate (re-write) oxidation/reduction half-cell reactions

To individual half-cell reaction:
1b. Balance elements (ignore H and O; these are balanced with \(H_2O\) later)
2b. Balance electrons transferred (i.e. change coeffients)
3b. Balance charges with: \(\color{blue}{OH^-~in~base}\) or \(\color{red}{H_3O^+~in~acid}\)
4b. Balance H’s and O’s with \(H_2O\)
5b. Recombine half-reactions and cancel out redundancies.
