- Limestone
- Limestone cycle
- Calcium Carbonate CaCO3
- Calcium hydroxide solution limewater Ca(OH)2
- Calcium hydroxide slaked lime Ca(OH)2
- Calcium oxide quicklime CaO + CO2
- Calcium Carbonate CaCO3
- Calcium hydroxide solution limewater Ca(OH)2
- Calcium hydroxide slaked lime Ca(OH)2
- Calcium oxide quicklime CaO + CO2
- Used for cement
- Neutralises acidic soil
- Calcium oxide quicklime CaO + CO2
- Test for carbon dioxide- if you bubble gas through it the solution will turn cloudy if carbon dioxide is present, the cloudiness is caused by a formation of calcium carbonate.

- Calcium Carbonate CaCO3
- Uses
- Blocks for building
- Mortar (limestone, sand, cement and water)
- Concrete (limestone, sand, cement, rock chippings)
- Glass
- Slaked lime-calcium carbonate+water can be used to neautralise acidic soils and lakes
- Quarrying
- Disadvantages
- Makes huge ugly holes which permanently change the landscape
- Quarrying processes like blasting rocks apart with explosives make lots of noise and dust in quiet scenic areas
- Destroys the habitats of animals and birds
- The limestone needs to be transported usually by lorries and this causes noise and pollution
- Advantages
- Limestone provides things that people want like houses and roads
- Limestone products are used to neutralise acidic soil
- Limestone is used in power station chimneys to neutralise sulphur dioxide which is a cause of acid rain
- Provide jobs for people
- Disadvantages
- Limestone products
- Widley available and is cheaper than granite or marble
- Easy to cut
- Hardwearing
- Very quick and cheap way of contructing buildings
- Concrete doesn't corrode like a lot of metals do
- Concrete is very unattractive
- Limestone cycle
- Heat- thermal decomposition
- Add water
- Add more water
- Add CO2 carbon dioxide
