Quicklime with Water
- Quicklime = CaO
- Water = H₂O
CaO + H₂O = Ca(OH)₂
Ca(OH)₂ is called Lime water & Slaked Lime.
This reaction is categorised for producing “heat energy”.
On touching the test tube we can feel the surface to be hot, which is symbolic example of chemical reaction.
Which means that, there is rise in temperature when Ca(OH)₂ is formed under reaction.
