Question

By passing $H_2S$ gas in acidified $KMnO_4$ solution, we get

• A. S
• B. $K_2S$
• C. $MnO_2$
• D. $K_2SO_3$

Answer 1

Answer: (A)

S

Answer 2

$2KMnO_4\, +5H_2S + 3H_2SO_4 \, \longrightarrow$
$\, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, K_2SO_4 \, + \, 5S \, + \, 2MnSO_4 \, + \, 8H_2 O$
