Question

Which of the following reaction(s) is/are correct regarding $K{O}_2$?

• A. $2K{O}_2+2H_{2}O\to 2KOH+H_2{O}_2+O_2$
• B. $2K{O}_2+CO\to K_{2}C{O}_3+O_2$
• C. $4K{O}_2+2C{O}_2\to 2K_{2}C{O}_3+3O_2$
• D. $2K{O}_2+S\to K_{2}S{O}_4$

Answer 1

Answer: (A), (B), (C), (D)

$2K{O}_2+S\to K_{2}S{O}_4$

$K{O}_2$ is prepared by burning potassium in excess of oxygen free from moisture.
$K+O_2\to K{O}_2$
All the reactions given in options are correct regarding $K{O}_2$.
