Question

The pH of an aqueous solution of H2O2 is 6.0 text . Some chlorine is bubbled through this solution. The pH of the resultant solution will be: (A) 6 (B) 7 (C) less than 6 (D) more than 7

When chlorine is passed through the solution of textH text2 textO text2 text, hydrochloric acid is produced. Due to this HCl acidity of solution increases. Hence, pH will decreased. textH2O2+Cl2 xrightarrow2HCl+O2 So, pH will be less than 6.

Q. The pH of an aqueous solution of $H_{2} O_{2}$ is $6.0 .$ Some chlorine is bubbled through this solution. The pH of the resultant solution will be:

6

7

less than 6

more than 7

When chlorine is passed through the solution of $H_{2} O_{2},$ hydrochloric acid is produced. Due to this HCl acidity of solution increases. Hence, pH will decreased. $H_{2} O_{2} + C l_{2} 2 H Cl + O_{2}$ So, pH will be less than 6.

Q. The pH of an aqueous solution of H2​O2​ is 6.0. Some chlorine is bubbled through this solution. The pH of the resultant solution will be:
