Question

What happens when CO2(g)
is passed through slaked lime?Write the balanced
chemical equation.Write the type of reaction that has occured.

Answer 1

Answer:

It is exothermic reaction

Explanation:

When CO2 is passed through Slaked lime we will observe a milky solution. This is due to the insoluble suspension of calcium carbonate formed: Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l).

Answer 2

Concept introduction:

Calcium carbonate, often known as CaCO$3$, is created when carbon dioxide combines with limewater, a solution of calcium hydroxide (Ca(OH)$2$). The precipitate dissolves to create a colorless solution of calcium hydrogen carbonate when more carbon dioxide is added.

Explanation:

Given that, CO$2$(g) is passed through slaked lime.

We have to find, balanced equation of carbon dioxide and slaked lime.

According to the question,

If CO$2$ is passed through slaked lime then calcium carbonate is formed due to which the solution turns milky. The equation is :

$Ca(OH)2(aq) + CO2(g) -------- CaCO3(s) + H2O(l).$

Final Answer:

When carbon dioxide is passed through slaked lime the lime water turns milky.
