Question

What is the reaction of calcium oxide with water?

Answer 1

Calcium Oxide

• Quicklime, or calcium oxide, is an alkaline material that has been used since the Middle Ages.
• Quicklime is thought to be one of the oldest compounds ever discovered by humans.
• Burnt lime or lime are other names for it.
• The chemical compound calcium oxide, also known as lime, has the formula $\mathrm{CaO}$.

The reaction between Calcium oxide and Water

• Calcium hydroxide is formed when calcium oxide (commonly known as quick lime) mixes with water (commonly known as slaked lime).
• The reaction can be shown as:
• $\mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)\stackrel{}{\to }\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{s}\right)$
• Calcium hydroxide, often known as slaked lime, is the end product of this process.
• A combination reaction is exemplified by this reaction.
