Question

How to balance redox reactions by the ion electron method?

Answer 1

⭕️Identity and separate out the oxidation and reduction.

⭕️Now, add the required number of electrons on correct side.

✔️✔️Note :-

➖Oxidation electron will be on RHS.

➖ Reduction electron will be on LHS.

⭕️Balance each 1/2 reaction with respect to charge and mass using the medium given.

⭕️Equate the number of electrons on both sides.

⭕️Now finally add both the half recations!!!!!!

⭕️DONE!!!!!!!

Step 2. Separate the redox reaction into half-reactionsa) Assign oxidation numbers for each atomb) Identify and write out all redox couples in reactionc) Combine these redox couples into two half-reactions

Step 3. Balance the atoms in each half reactiona) Balance all other atoms except H and Ob) Balance the oxygen atoms with H2Oc) Balance the hydrogen atoms with H+d) In a basic medium, add one OH-to each side for every H+
