Group 2: General Properties - Chemistry LibreTexts
Calcium carbonate is a component of shells in living organisms, and is used as a commercial antacid. It is also the main component of limestone. As shown below, three steps are required to to obtain pure \(CaCO_3\) from limestone: calcination, slaking, and carbonation.
Lime (calcium oxide) and slaked lime (calcium hydroxide) are both used to reduce the acidity of soil on land, they are both faster and stronger acting than limestone powder. Plants grow best within a certain pH range, over acidity can affect plant growth, adding powdered limestone or lime to the soil neutralises the acid and raises the pH to improve crop growth.
