Strontium Carbonate: Powdered Celestine Boiled with Soda Solution (Thorpe 1912)

Celestine, the natural strontium sulphate, boiled with a solution of sodium carbonate turns into strontium carbonate, while the sulphate goes into the solution. Source: Thorpe, Dictionary of Applied Chemistry vol. 5 (1912), Strontium, after Trachsel (1886). Not given: amounts, strength or time; washing and drying are ours. Picture drawn by Youblob.

Instructions

Powder the celestine

Grind celestine to a powder.

Materials for this step:

Celestine1 as required

Tools needed:

Mortar and Pestle

Boil it with sodium carbonate solution

Boil the powdered mineral with a solution of sodium carbonate. It becomes strontium carbonate. Not given: amounts, strength or time. Goggles for the hot alkali.

Materials for this step:

Sodium Carbonate (soda ash)1 as required

Water1 as required

Tools needed:

Borosilicate Beaker

Hot Plate

Chemical Splash Goggles

Wash and dry

Ours: filter off the carbonate, wash it well with water to remove the sodium sulphate, and dry it.

Tools needed:

Filter Paper

Water

Drying Oven
