Question

When $CO_{2}$is bubbled through a solution of barium peroxide in water ?

• A. Carbonic acid is formed
• B. $H_{2}O_{2}$is formed
• C. $H_{2}O_{2}$is formed
• D. Barium hydroxide is formed.

Answer 1

Answer: (B)

$H_{2}O_{2}$is formed

Answer 2

: When $Co_{2}$is bubbled through a cold solution of barium peroxide in water, $H_{2}O$is obtained.

$BaO_{2} + CO_{2} + H_{2}O \rightarrow BaCo_{3} \downarrow + H_{2}O_{2}$
