Question

Euchlorine is

• A. obtained by heating perchlorate with conc. $HCl$
• B. a chloride of europium
• C. a mixture of $C{l}_{2}andC{l}_2{O}_7$
• D. a mixture of $C{l}_{2}andCl{O}_2$

Answer 1

Answer: (D)

Euchlorine is a rare emerald-green colored sulfate mineral found naturally occurring as a sublimate in fumaroles around volcanic eruptions.
When $KCl{O}_3$ is heated with conc. HCl, a mixture of $C{l}_2$ and $Cl{O}_2$ is formed. The mixture is known as euchlorine.
$2KCl{O}_3+4HCl\to 2KCl+2Cl{O}_2+C{l}_2+2H_{2}O$
