- Limestone
- Calcium Carbonate
- When heated, it breaks down
- Calcium Oxide
- Quicklime
- Yellow when hot, white when cold
- Limestone (heat)--> Quicklime + Carbon Dioxide
- Reacts with water to form Calcium Hydroxide
- Slaked Lime
- A white powder
- Used to make Limewater
- Quicklime + water --> Slaked Lime
- Used in building work
- Slaked Lime
- Quicklime
- Carbon Dioxide
- Test for Carbon Dioxide is: Limewater turns cloudy
- This is called Thermal Decomposition
- Equation for Thermal Decomposition of Calcium Carbonate: CaCO3 (heat)---> CaO + CO2
- Calcium Oxide
- When heated, it breaks down
- Uses
- Used to make Mortar
- Used to make Cement
- Used to make Concreate
- Used to make Glass
- Used to neutralize acidic soil for crops and lakes
- Used to Purify Iron in blast furnaces
- Ingredient of toothpaste
- Calcium Carbonate
- is basically
- which is basically
