The pH of a solution of `H_2O_2` is 6.0. Some chlorine gas is bubbled into this solution. Which of the following is correct?

A

Hydrogen gas is liberated.

B

The pH of resultant solution becomes 8.0.

C

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

D

`Cl_2O` is formed in the resultant solution.

Text Solution

Verified by Experts

The correct Answer is:
C
`H_2O_2 + Cl_2 to 2HCl + O_2`
As HCl (a strong acid ) is produced , hence `[H^+]` of the solution increases, pH of the solution decreases.
