What is iodometric titration?
In this titration iodine is liberated .... Added: ... from (excess of) iodide by an oxidant. The Iodine is then titrated with thio (di-sodium thio-sulfate) and starch as indicator added just before the expected equivalence point. Read More »

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 io... Read More »

I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion.== Answer == So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Pota...

Actually, one determines SO2 by iodometry. It is oxidized to H2SO4 in water solution. You titrate to the disappearance of the brown color of I2. I don't remember if one can use starch indicator or not. 2H2O + I2 + SO2 ===> H2SO4 + 2HI

In iodometric titrations sodium thiosulfate is the titrant whereas the KI will reduce the analyte; eg: Cu 2+ to Cu +. The I 2 produced is then titrated by the sodium thiosulphate. Cu 2+ + I - --> CuI + I 3 - I3- + 2 S2O32- ¾® 3 I- + S4O62- ...
