Question

How is slaked lime is obtained by lime stone.

Answer 1

Answer:

Slaked lime is made by combining CaO with water so that the CaO converts to Calcium Hydroxide, Ca(OH)2. ... When limestone is heated to high temperatures (around 1000 degrees c )in an oxygen rich atmosphere it breaks down into calcium oxide and carbon dioxide

Answer 2

Slaked lime can be obtained by lime stone by reacting it with water.

Explanation:

• Chemically, lime stone is calcium carbonate, the natural and the most common form in which calcium exists in nature.
• First these calcium carbonate is mined from the earth, and then it is crushed to form various small pieces of calcium carbonate is burnt in a kiln and the residual water escapes it. The end product is called as Calcium oxide, or quicklime.
• Now this quick lime or calcium oxide is mixed with water to form slaked lime or chemically calcium hydroxide.
• The commercial production of calcium hydroxide or slaked lime is prepared by this process.
• Slaked lime has various commercial uses in building materials like concrete, cement, mortar, etc.
• The process of mixing calcium oxide with water to form calcium hydroxide is highly exothermic in nature.
