Thiosulfate is a reducing agent. It is routinely used as a titrant to determine concentrations of oxidants such as hypochlorite in bleach and dissolved oxygen in water. It instantly dechlorinates water, and is used to stop bleaching action in the paper-making industry.
What is the charge on thiosulphate?
-2 charge
Thiosulfate has a central sulfur atom surrounded by three oxygen atoms and one sulfur atom. Specifically, a double bond is present between the bonding of two oxygen atoms to the sulfur atom. Keep in mind that thiosulfate is an ion. This explains the presence of a -2 charge in its structure.

What is Tetrathionate ion?
The tetrathionate anion, S. 4O 2− 6, is a sulfur oxoanion derived from the compound tetrathionic acid, H2S4O6. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation state +5. Alternatively, the compound can be viewed as the adduct resulting from the binding of S 2−
What is ClO element?
Hypochlorite is an ion composed of chlorine and oxygen with the chemical formula ClO−.
What is the formula of tetrathionate ion?
Tetrathionate is one of the polythionates, a family of anions with the formula [Sn(SO3)2]2−. Its IUPAC name is 2-(dithioperoxy)disulfate, and the name of its corresponding acid is 2-(dithioperoxy)disulfuric acid. The Chemical Abstracts Service identifies tetrathionate by the CAS Number 15536-54-6.
What is the molecular geometry of S2O3 2?
In S2O3 2- the central sulfur atom is bonded to 1 sulfur and 3 oxygens with no lone pairs so there are 4 regions of electron density which must be arranged tetrahedrally.
What ion is ClO?
Hypochlorite
Hypochlorite is an ion composed of chlorine and oxygen with the chemical formula ClO−. Being unstable in the pure form, hypochlorite is most commonly used for bleaching, disinfectation, and water treatment purposes in its salt form, sodium hypochlorite.
What is ClO called?
Chlorine monoxide is a chemical radical with the chemical formula ClO•.
What is the tetrathionate anion?
The tetrathionate anion, S. 4O 2−. 6, is a sulfur oxoanion derived from the compound tetrathionic acid, H 2S 4O 6. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation state +5. Alternatively, the compound can be viewed as the adduct resulting from the binding of S 2−.
What is the oxidation number of sulfur in tetrathionate?
Tetrathionate. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation state +5. Alternatively, the compound can be viewed as the adduct resulting from the binding of S2− 2 to SO3. Tetrathionate is one of the polythionates, a family of anions with the formula [S n (SO 3) 2] 2−.
What is the IUPAC number for tetrathionate?

How do you make m broth from tetrathionate?
Incubate the tetrathionate broth in a 42 ± 0.5°C water bath and the selenite cystine in a 35°C water bath for 6–8 h. After incubation, transfer 1.0 ml of tetrathionate mixture to a 10 ml tube of sterile M broth with 10 μg ml −1 novobiocin; label as ‘M broth Tet’.
