Product Description

Sodium selenite is the inorganic compound with the formula Na2SeO3. This salt is a colourless solid. The pentahydrate Na2SeO3(H2O)5 is the most common water-soluble selenium compound. Sodium selenite is mainly used in the manufacture of colorless glass. The pink color imparted by these selenites cancels out the green color imparted by iron impurities.

Because selenium is an essential element, sodium selenite is an ingredient in some food supplements. The US Food and Drug Administration approved a selenium supplement to animal diets, however the most common form is sodium selenite for pet foods.

Sodium Selenite Pentahydrate BP Grade: Ph Eur Na2SeO3,5H2O -- 263.0 -- 26970-82-1

DEFINITION: Content: 98.5 per cent to 101.5 per cent.

IDENTIFICATION

Dissolve 50 mg in 5 ml of a mixture of equal volumes of dilute hydrochloric acid and water and heat to boiling. Add 0.05 g of ascorbic acid; a red precipitate is formed which may become black.
Dissolve 50 mg in a mixture of 1 ml of dilute hydrochloric acid and 5 ml of water. Add 1 ml of barium chloride solution; the solution remains clear.
It gives reaction of sodium.
It complies with the limits of the assay.

Sodium Thiosulphate Pentahydrate Price : 45 INR Minimum Order Quantity : 100 Appearance : White Crystalline Shape : Crystal CAS No : 10102177 (7772987 Anhydrous) Usage : Sodium thio sulfate is also used: As a component in hand warmers and other chemical heating pads that produce heat by exothermic crystallization of a supercooled solution. In bacteriological water assessment, as it promotes the survival of coliform organisms by neutralizing residual chlorine.[15]:249[16]:572 In the tanning of leather To demonstrate the concept of super cooling in physics classes: Sodium thio sulfate, when heated, dissolves in its own water of crystallization. This solution can be cooled to room temperature without re crystallization. When crystallization is induced by the addition of a small seed crystal, the sudden temperature rise can be experienced by touch.
