Balance the equation by ion electron method. PbO2 + Cl– → ClO– – InterviewSolution

1.

Balance the equation by ion electron method. PbO2 + Cl– → ClO– + [Pb(OH)3]– in basic solution.

Answer»

Here

2e^– + PbO₂ → [Pb(OH)₃]^–

2H₂O + 2e^–PbO₂² → [Pb(OH)₃] + OH^– …(i)

2OH + Cl^– → ClO^– + 2e^– + H₂O …(ii)

Add (i) & (ii)

PbO₂ + OH^– + Cl^– + H₂O → [Pb(OH)₃]^– + ClO^–
