How plaster of Paris is related with Paris?

Answer 1

Gypsum The gypsum is heated to about 1500C to remove its H2O (water) content. It becomes a dry powder, with the chemical name gympsum hemihydrate or, more accurately calcium sulfate hemihydrate. CaSO4.1/2H2O

Answer 2

You can not actually make Plaster or Paris because it is taken from the ground and modified. However, you can make a mock version of it with flour and water. You simply take two cups of warm water and three cups of all-purpose flour and mix them together until you get a paste-like consistency. One set back with this mock version though is that it will quickly set and you won't be able to use it again once it cools.

Answer 3

Plaster of Paris is made from Gypsum CaSO4·2H2O. Note that it has two molecules of water (H2O) in its crystal structure.

If you heat Gypsum then waster is released thus 2 CaSO4·2H2O → 2 CaSO4·0.5H2O + 3 H2O (as steam). The 2 CaSO4·0.5H2O is a powder called Plaster of Paris.

When you add water back to the Plaster of Paris powder, then Gypsum is reformed and the powder solidifies.

Answer 4

Plaster of Paris gets its name from the fact that gypsum in its hydrated form was historically sourced from Montmartre in Paris, France. This material was widely used in the 19th century for sculpting and casting due to its ease of use and quick drying properties, and hence it became known as Plaster of Paris.

Answer 5

the term plaster of Paris was given because the product was obtained by burning the gypsum mineral from the deposits near Paris

Answer 6

the plaster is named 'de Paris' because the raw material came from the gypsum quarries in the Seine valley near Paris (for example around Triel sur Seine west of Paris).

Answer 7

Plaster of Paris is essentially calcium sulfate (CaSO4) with a little water attached.

Answer 8

Plaster of Paris is calcium sulfate - CaSO4.0,5H2O.

Answer 9
