Question

H2O2 + CL2 --- HCL + H2O + O2 BALANCE BY PARTIAL EQUATION

Open in App

Solution

The partial equation are as follows :

1) Oxidation half reaction : (oxidation state of O changes here from -1 to 0.)
H₂O₂ ------ > O₂ + 2e- + 2H⁺

2)Reduction half reaction :
Reduction of Cl₂ to Cl^- occurs
Cl₂ + 2e^- ----> 2Cl^-

Thus overall reaction is
H₂O₂+ Cl₂----> 2HCl +O₂
