Question

$Cl_{2} \left(g\right) Ba \left(OH\right)_{2} \quad\quad X\left(aq\right) + BaCl_{2} + H_{2}O$
$\begin{matrix}X&H_{2}SO_{4}&Y + BaSO_{4}\\ Y&_{T >365K}&Z+H_{2}O+O_{2}\end{matrix}$
Y and Z are respectively :

• A. $HClO _{4} ClO _{2}$
• B. $HClO _{3}, ClO _{2}$
• C. $HClO _{3}, ClO _{6}$
• D. $HClO _{4}, Cl _{2} O _{7}$

Answer 1

Answer: (B)

$6 Cl _{2} \quad 2 Ba ( OH )_{2} \quad Ba \left( ClO _{3}\right)_{2}+5 BaCl _{2}+6 H _{2} O$
$Ba \left( ClO _{2}\right)_{2} \ldots HSO _{4} \quad 2 HClO _{3} \quad BaSO _{4} .$
$2 HClO \quad 265 K \quad 2 ClO _{2}+ H _{2} O +\frac{1}{2} O _{2}$
