With 'sodium thiosulfate' (two words!) and bromine the reaction will be strong to give oxidised tetrathionate and reduced bromide: 2 S2O32−(aq) + Br2(aq) → S4O62−(aq) + 2 Br−(aq)

What is the use of Sodium thiosulphate in iodometry?
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
Why do you use starch to standardise sodium thiosulphate using potassium iodate?
The iodine produced from the KIO3 reacts with the starch to produce the blue black colour used as the indicator
Why sodium thiosulphate is called hypo?
Because it used to be called Sodium hyposulphite.
Why is sodium thiosulphate stored in a brown bottle?
Because it is :)
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
What is a bromine neutralizer?
Sodium thiosulphate solution (5-25 %)
Does bromine react with soduim?
Yes: Bromine reacts with sodium to form sodium bromide.
What happens when bromine reacts with sodium?
Sodium bromide(NaBr) is formed
Why does when sodiumbromide reacts with chlorine the solution turns yellow?
Sodium bromide reacts with chlorine to produce sodium chloride and bromine. 2NaBr + Cl2 --> 2NaCl + Br2. Bromine in color, though may appear yellowish in low concentrations.
Why is sodium thiosulphate used in iodometric titration?
· In analytical chemistry, sodium thiosulphate is used for the determination of the strength of a given solution of iodine. · Sodium thiosulphate is preferred in iodometric analysis due to the fact that sodium thiosulphate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents.

What is the reaction of sodium sulphite and sulphur?
sodium thiosulphate
What ionic compound has a orange flame with sparks when it is burnt?
I'm not sure but I know that when sodium reacts with bromine it does that.
Is sodium thiosulphate a reactant?

What is the difference between sodium sulphate and sodium thiosulphate?
The polyatomic anions in sodium sulphate have the formula SO4-2, while the polyatomic anions in sodium thiosulphate have the formula S2O3-2.
What happen when you mix Sodium Hydroxidex Iron Chloride?
you get magnesium bromine
Is sodium thiosulphate an acid or a base?
Sodium thiosulphate is a somewhat strong acid with pKas of 0.6 and 1.7 for the first and second dissociation respectively.
