Question

$H_{2}S$ cannot be dried by passing over concentrated $H_{2}S{O}_4$ because:

• A. the acid oxidises $H_{2}S$
• B. the acid combines with $H_{2}S$ to from a salt
• C. both form a complex after mixing
• D. $H_{2}S$ dissovles in acid and increases its concentration

Answer 1

The correct option is A the acid oxidises $H_{2}S$

The acid oxidises $H_{2}S$.
$H_{2}S{O}_4+H_{2}S⟶S+S{O}_2+2H_{2}O$
