- Limestone and Building Materials
- Limestone/ Calcium carbonate (CaCO3)
- Adding heat gives you calcium oxide (CaO)
- Add water to produce calcium
hydroxide (Ca(OH)2)
- This is an alkali that can be used in the neutralization of acids
- Add more water to get calcium hydroxide solution (Ca(OH)2)(aq)
- Add carbon dioxide to get calcium carbonate
- Limestone/ Calcium carbonate (CaCO3)
- Adding heat gives you calcium oxide (CaO)
- Add water to produce calcium
hydroxide (Ca(OH)2)
- This is an alkali that can be used in the neutralization of acids
- Add more water to get calcium hydroxide solution (Ca(OH)2)(aq)
- Add carbon dioxide to get calcium carbonate
- Add carbon dioxide to get calcium carbonate

- Thermal decomposition- Breaking down a substance with heat
- Calcium carbonate thermally decomposes into calcium oxide and carbon dioxide
- Metal carbonates thermally decompose to make a metal oxide and carbon dioxide
- eg the carbonates of magnesium, copper, zinc, calcium and sodium
- Limewater is used as a test for carbon dioxide. Carbon dioxide turns limewater cloudy
- Carbonates react with acids to produce carbon dioxide, a salt and water.
- Limestone is damaged by acid rain. (sulfur dioxide and nitrogen oxides)
- Limestone + clay + heat = cement
- Cement + sand = mortar
- Cement + sand + aggregate (small rocks) = concrete
- Cement + sand = mortar
- Limestone/ Calcium carbonate (CaCO3)
