Factory Supply Sodium Thiosulfate /Sodium Thiosulphate CAS 7772-98-7

Sodium Thiosulphate, also called thiosulfuric acid or disodium salt, is an inorganic salt that is also available in pentahydrates. This chemical substance has a chemical formula of Na2S2O3. It appears as a bright white colourless crystal or even in powder form. The substance is known to possess alkaline nature when decomposed to sulphide and sulfate in the air.

Sodium thiosulfate readily dissolves in water giving thiosulfate ions, which is one of the useful reducing agents. The Copper (II) sulfate dissolves to give the cupric ion; in regard to a redox reaction with the thiosulfate, the cupric particles act like oxidising agents.

Sodium Thiosulphate possesses various chemical and physical properties as given below:

• Sodium thiosulphate appears as a white translucent, colourless crystal and is an inorganic compound.
• It is a water-soluble substance and is also soluble in the oil of turpentine but not in alcohol.
• The substance has a melting point of about 48 to 52 C.
• This chemical substance is highly stable in nature and is said to be incompatible with some strong oxidising agents and strong acids.
• Thiosulfate anion readily reacts with the dilute acids producing sulphur, sulphur dioxide and also water.
• The chemical has a density measuring about 1.667 g/mL.
