How is iodine estimated in ccl4 and h2o layer?
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.
0.1N Sodium Thiosulphate is primary or secondary solutions?
it is a secondary solution because it can change its concentration by absorbing moisture....
What is a bromine neutralizer?
Sodium thiosulphate solution (5-25 %)
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.
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
to acidify the solution
Indicator used during the standardization of sodium thiosulphate?
Starch

Why is standardization of sodium chloride solution with the help of known silver nitrate solution needed?
Sodium chloride may be used as standard (for example to prepare sodium solutions with known concentration) because is a stable compound.
What is a bromin?
Sodium thiosulphate solution (5-25 %)
Why sodium carbonate is used in preparation of thiosulphate solution?
To ensure the stability of the solution

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 sodium thiosulphate solution is prepared in freshly boiled and cooled water?
why sodium thiosulfate to be prepared in hot water only
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
to acidify the solution
Is sodium thiosulphate solution a primary standard?
No. because it contains water of crystallization so it can absorb or release water..
