Question

What does passing of carbon dioxide through slaked lime give?

Answer 1

Hint: When we pass carbon dioxide through slaked lime it gives calcium carbonate and water. The reaction is highly exothermic in essence, an exothermic process describing a process or reaction that releases energy from the system to its surroundings.

Complete answer:
If $C{O_2}$ is passed through slaked lime, it gives out calcium carbonate $(CaC{O_3})$ also called marble/limestone. This is due to the insoluble suspension of calcium carbonate formed. The reaction is:
This is a highly exothermic reaction. The balanced chemical reaction can be expressed as:
$Ca{(OH)_2} + C{O_2} \to CaC{O_3} + {H_2}O$
When calcium hydroxide is treated with carbon dioxide, the calcium carbonate and water is formed, then carbon dioxide is released.

Additional information:
Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Calcium is needed by the body for healthy bones, muscles, nervous system, and heart. Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach.
Side effects of calcium carbonate:
Little or no urinating, swelling, rapid weight gain, or. High levels of calcium in your blood -nausea, vomiting, constipation, increased thirst or urination, muscle weakness, bone pain, confusion, lack of energy, or feeling tired.

Note:
Remember carbon dioxide is acidic in nature and calcium hydroxide is base. So, the neutralization reaction occurs. It is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
