Question

When $C{O}_2$ is passed through lime water, it turns milky. Identify the cause of the milkiness.

• A. Formation of $Ca(OH{)}_2$
• B. Formation of $H_{2}O$
• C. Formation of $CaC{O}_3$
• D. Formation of $H_2$

Answer 1

The correct option is C Formation of $CaC{O}_3$

When $C{O}_2$ is passed through lime water, it turns milky due to the formation of a white insoluble suspension of $CaC{O}_3$.
$Calciumhydroxide+carbondioxide\to Calciumcarbonate+water$
