The balanced skeleton reactions are given below
2CrO₄²⁻(aq) + 3Cu(s) +8(l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6(aq)
The oxidising agent and reducing agents are Cr and Cu .
There are following steps involve in balance redox reaction in basic medium .
- First divide the reaction into two half reactions which give oxidation and reduction half reaction.
- Then balance the elements other than oxygen and hydrogen atom.
- Balance the oxygen atom by adding where number of oxygen is less .
- Balance the hydrogen atom by adding on another side of where water molecule added.
- Add ions to both sides to neutralize ion.
- Combine and ion to make .
- Balance the charge by adding .
The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .
