identify the compound of calcium which is used for plastering of fractured bones??
with the help of equation describe how this compound is prepared?
special precautions taken while preparing this compound??
Calcium Sulphate hemihydrate is used for plastering of fractured bones.
On heating gypsum at 373 K or 100 degree celcius the water molecules are lost and Plaster of Paris or Calcium Sulphate Hemihydrate is formed.
CaSO4.2H20 = (at 100 degree celcius) CaSO4.1/2 H2O + 1 1/2 H20
Plaster of Paris changes to Gypsum in the presence of moisture. This Gypsum sets as a hard solid mass and thus plaster of paris ecomes useless.
If this was useful pls give thumbs up
