The pH of a solution of H ₂ O ₂ is 6.0. Some chlorine gas is bubbled into this solution. Which of the following is correct?
Options
- AThe pH of resultant solution becomes 8.0
- BHydrogen gas is liberated from resultant solution
- CThe pH of resultant solution becomes less than 6.0 and oxygen gas is liberated
- DCl ₂ O is formed in the resultant solution
Correct answer
C. The pH of resultant solution becomes less than 6.0 and oxygen gas is liberated
Step-by-step solution
H ₂ O ₂+ Cl ₂ 2 HCl + O ₂ HCl is formed by the reduction of chlorine by H ₂ O ₂ , hence pH further decreases.
