Answer 2

$CO_2, SO_2$ get absorbed by KOH.

• KOH is a base and shows basic properties.
• The acid will be easily soluble in a base. So, any acid will easily be soluble in KOH.
• Carbon Dioxide and sulfur dioxide are acidic gas. They show acidic properties.
• Thus $CO_2, SO_2$ are easily absorbed by KOH which is a base.
• So, $CO_2, SO_2$ get absorbed by KOH.
