Question

what are the steps to balance the redax reaction by ion electron method in a acidic medium

Answer 1

steps of ion electron method :---

Step 1. Write down the unbalanced equation

Step 2. Separate the redox reaction into half-reactions

a) Assign oxidation numbers for each atom
b) Identify and write out all redox couples in reaction
c) Combine these redox couples into two half-reactions

Step 3. Balance the atoms in each half reaction

a) Balance all other atoms except H and O
b) Balance the oxygen atoms with H2O
c) Balance the hydrogen atoms with H+
d) In a basic medium, add one OH- to each side for every H+
Step 4. Balance the charge with e-

Step 5: Make electron gain equivalent to electron loss in the half-reactions

Step 6: Add the half-reactions together

Step 7: Simplify the equation

Finally, check that the elements and charges are balanced

this is your answer.....
