Answer:
Explanation:
When quick lime is added to water, the following reaction takes place. Here,CaO is quick lime and Ca(OH)2 is slaked lime.
CaO + 2H₂O —> Ca(OH)₂ + H₂
Lime (calcium oxide) is a white solid with strongly basic properties.
Lime reacts readily with water to produce slaked limeThe common name for calcium hydroxide. When water is added to lime (calcium oxide), a chemical reaction occurs converting it into slaked lime (calcium hydroxide)., which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction.
Calcium hydroxide is sparingly soluble in water producing an alkaline solution known as limewater. When carbon dioxide gas is passed through or over limewater, it turns milky due to the formation of calcium carbonate.
