How to make calcium hydroxide from limestone? Calcium hydroxide is produced commercially by treating lime with water: CaO + H2O → Ca(OH) In the laboratory it can be prepared by mixing aqueous solutions of calcium chloride and sodium hydroxide.
How do you make calcium oxide from limestone? Calcium oxide or lime is prepared by the process called calcination. Calcium carbonate or Limestone is heated to a temperature between 1250 ⁰C and 1400 ⁰C in Kilns (oven) and it decomposes to quicklime and carbon dioxide.
How is calcium hydroxide made? Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.

How calcitonin helps blood calcium levels?
By preventing the breakdown of bone, calcitonin lessens the amount of calcium in the blood. The hormone also seems to decrease the amount of calcium the kidneys can re-absorb, lowering levels further. Secretion of this hormone is controlled directly by the blood’s calcium levels.
