sodium sulfate thenardite

Thenardite Saltwiki

The only stable forms of sodium sulfate are the decahydrate (mirabilite) and the anhydrite (thenardite). The generation of mirabilite by recrystallization of the salt from an aqueous supersaturated solution occurs at 32.4°C.

THÉNARDITE Encyclopædia Universalis

18/03/2020· On rencontre dans la nature deux formes de sulfates de sodium : la thénardite Na 2 SO 4 et la mirabilite Na 2 SO 4.10 H 2 O. Comme le sulfate de sodium est dix fois plus soluble à  30 0 C qu'à 0 0 C, la précipitation a lieu, le plus souvent, sous forme de mirabilite pendant la saison froide, dans des lacs salés où la saturation en ce sel peut être obtenue.

THENARDITE (Sodium Sulfate) Amethyst Galleries

Thenardite is one of several non-marine evaporite Sulfate Class minerals. It is easily dissolvable in water and specimens should be stored with desiccant. Sulfates in general tend to be more soluble than most of the other mineral classes and simple sodium salts, such as thernardite, are always soluble. As one might imagine, thenardite forms in arid regions as a salty precipitate as well as in

Home Sodium Sulphate

Sodium sulfate anhydrous, also known as thenardite, has a formula of Na2SO4. It has an appearance of white crystalline solid and is chemically very stable. It is unreactive toward most oxidizing or reducing agents at normal temperatures. In addition to that, it can be converted to sodium sulfide at high temperature by carbo-thermal reduction.
