Is CaO an alkali?
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.
It is a white, caustic, alkaline, crystalline solid at room temperature..
What happens when quicklime dissolves in water?
When Calcium oxide i.e. quick lime is added to water filled in a bucket, it reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat.
What happens when CaO reacts with water?
The formation of slaked lime (calcium hydroxide, Ca(OH)2) when water is added to lime (CaO) is exothermic. CaO(s) + H2O (l) → Ca(OH)2(s) This reaction occurs when water is added to dry portland cement to make concrete, and heat evolution of energy as heat is evident because the mixture becomes warm.
Does CaO react with water?
When calcium oxide (chemical formula: CaO) reacts with water (chemical formula: H2O), the following reaction takes place: The product of this reaction is calcium hydroxide, also known as slaked lime. Thus, when calcium oxide reacts with water, slaked lime is produced.
Which product will form when CaO is dissolved in water?
When water is added to calcium oxide (quicklime), it will be converted to calcium hydroxide (slaked lime) with the liberation of enormous amount of heat. CaO+H₂O=Ca(OH)²+heat It is an exothermic reaction.
How do you dissolve calcium oxide?
Pipette 4 ml of deionized distilled water in a 150-ml beaker. Place on a hot plate at a low heat and bring water to approximately 60°C. Place stirring rod in beaker and add 1 g pulverized calcium oxide slowly while stirring. If necessary, remove beaker from hot plate momentarily to control spattering.
