To ensure the stability of the solution
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
A sodium carbonate solution, or any solution for that matter, is a mixture.
A 1M solution of sodium carbonate contains 1 gram formula mass of sodium carbonate dissolved in each liter of solution.
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.
when their solution are mixed iron carbonate solid and solution of sodium sulphate is produced..
You could die.

Sodium thiosulphate solution (5-25 %)
Sodium thiosulphate solution (5-25 %)
· 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.

Sodium carbonate would be deposited at the bottom of the solution.
Sodium carbonate is added to increase the pH of the solution.
it is a transparent solution
