1 Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity. 2  Calcium carbonate can be used to remove acidic gases from coal-fired power station chimneys reducing harmful emissions and acid rain. We know this because the surroundings get warm. ] 2  reaction takes place. 3  This forms calcium hydroxide. 4  Calcium hydroxide is soluble in water and forms a solution known as limewater which is used to test for carbon dioxide. 5  Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity.
It is heated to form quicklime (CaO) which is then added to water (H 2 O). This forms another material known as slaked lime (Ca(OH) 2) which is an inexpensive base material used throughout the chemical industry. Chalk, marble and limestone are all forms of calcium carbonate.bout 4.2% of the earth's crust is composed of calcium. Due to its high reactivity with common materials, there is very little demand for metallic calcium. It is used in some chemical processes to refine thorium, uranium and zirconium. Calcium is also used to remove oxygen, sulfur and carbon from certain alloys.
