LIMESTONE
- Limestone is mainly calcium carbonate(CaCO3)
- Thermally decomposes when heated
to form calcium oxide(CaO) and CO2
- Calcium Oxide (CaO) reacts with
water to form Calcium hydroxide-Ca(OH)2
- Calcium Hydroxide is an
alkali
- can be used to neutralise acidic
soils so can powdered limestone
but the limestone works allot
slower.
- Calcium Hydroxide and water
solution (limewater) tests for
CO2 by turning cloudy if CO2
present due to calcium
carbonate(CaCO3) forming.

- Calcium Hydroxide is an
alkali
- Calcium Oxide (CaO) reacts with
water to form Calcium hydroxide-Ca(OH)2
- CaCO3 also reacts with acid to make a
calcium salt, CO2 and H2O
- Type of salt would depend on acid E.G
hydrochloric acid = a chloride salt
- Type of salt would depend on acid E.G
hydrochloric acid = a chloride salt
- Thermally decomposes when heated
to form calcium oxide(CaO) and CO2
- Powdered limestone can be
heated in a kiln with powdered
clay to make cement
- Cement mixed with sand and water forms
mortar, used to stick bricks together.
- Cement mixed with sand and
aggregate(water & gravel) makes
concrete
- Cement mixed with sand and water forms
mortar, used to stick bricks together.
