Question

When a carbon dioxide reacts with calcium hydroxide salts and water are

produced. Then the nature of carbon dioxide is​

Answer 1

Answer:

carbon dioxide will be acidic in nature because acid and base reacts to give salt and water.

Thanks

Answer 2

Calcium hydroxide, a base, combines with carbon dioxide to produce salt (calcium carbonate) and water.. As acids and bases combine to produce salt and water, carbon dioxide is acidic in nature.

Explanation:

A solid calcium carbonate precipitate and water are formed when an aqueous solution of calcium hydroxide or lime water combines with carbon dioxide gas. The calcium carbonate that results from the reaction is water insoluble.

The chemical equation for the preceding reaction is as follows:

Ca(OH)2(aq) + CO2 (g) → CaCO3(s) + H2O(l)

Reaction process:

• The process is a twofold displacement reaction.
• The calcium carbonate that forms is a precipitate that is not water soluble.
• Calcium carbonate is a white solid that can be found in nature. Due to the production of calcium carbonate, the solution appears milky.
• The reaction of calcium carbonate with carbon dioxide is also a precipitation reaction because it produces a white solid precipitate known as calcium carbonate.
