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.

What is the chemical symbol for sodium thiosulphate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
What is sodium thiosulphates chemical symbol?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Why do you use starch to standardise sodium thiosulphate using potassium iodate?
Starch acts as an indicator for the endpoint of the reaction between sodium thiosulphate and potassium iodate, as it forms a blue-black complex with iodine. This color change helps identify when all the iodine has been liberated from the reaction. This method is commonly used in titrations to determine the concentration of the sodium thiosulphate solution accurately.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Why is sodium thiosulphate stored in a brown bottle?
Sodium thiosulfate is photosensitive, meaning it degrades when exposed to light. Storing it in a brown bottle helps to block out light and prevent this degradation, maintaining the stability and effectiveness of the compound.
Why use sodium Bicarbonate for titration of sodium thiosulphate using pottasium dicromate?
because sodium thiosulphate is unstable and iodine also so to maintain neutral medium we have to use sodiumcarboate
What color is Sodium Thiosulphate?
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
What is a bromin?
Sodium thiosulphate solution (5-25 %)
Indicator used during the standardization of sodium thiosulphate?
Starch
What is the boiling point of sodium thiosulphate?
The boiling point of sodium thiosulphate is 100 degrees Celsius, the same as water.That would be 212 degrees Fahrenheit.
What does sodium thiosulphate and hydrochloric acid react to form?
sodium chloride, sulphur, sulphur dioxide and water
Is sodium thiosulphate conductive?
Sodium thiosulfate is not conductive because it does not dissociate into ions in solution. It is a non-electrolyte.
What is the chemical symbol for sodium thiosulphate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
What is the compound symbol of sodium bicarbonate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O. Hope that helps.
Which of the following is used as food preservative 1 sodium Benzoate 2 sodium Thiosulphate 3 sodium Hydroxide 4 sodium Bicarbonate?
1.sodium benzoate
Can sodium thiosulphate exists in liquid form?
Yes you can buy it online at yourashithead.fag
Why is starch indicator added after sodium thiosulphate?
Starch indicator is added after sodium thiosulphate in iodometric titrations to help visualize the endpoint of the reaction. Starch reacts with any excess iodine produced at the endpoint, forming a dark blue-black color, allowing for easier detection of when all the thiosulphate has reacted.
