The balanced skeleton reactions are given below
Cr₂O₇²⁻(aq) +3Zn(s) + 14(aq) → 3Zn²⁺(aq) +2 Cr³⁺(aq) + 7(l)
The oxidising agent and reducing agents are Cr₂O₇²⁻ and Zn.
There are following steps involve in balance redox reaction in acidic medium .
- First divide the reaction into two half reactions .
- Balance the elements other than oxygen and hydrogen atom.
- Balance the oxygen atom by adding on that side where number of oxygen atom is less .
- Balance the hydrogen atom by adding on another side of in which water attached .
- Balance the charge by adding .
- Add the two half reaction .
The species which reduces the other species in the redox reaction is called reducing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .
