The $pH$ of the resultant solution becomes less than $6.0$ and oxygen gas is liberated

(C) $H_2O_2 + Cl_2 \longrightarrow 2HCl + O_2$ In this reaction,$H_2O_2$ acts as a reducing agent and reduces $Cl_2$ to $HCl$. The formation of $HCl$ (a strong acid) increases the concentration of $H^+$ ions in the solution. Consequently,the $pH$ of the resultant solution decreases to a value less than $6.0$,and oxygen gas $(O_2)$ is evolved.
