No, reaction
The only known and possible reaction is the following redox (reduction-oxidation) reaction between I3- (Iodine-Iodide complex) and S2O32- (thiosulfate)I3- + 2 S2O32- --> 3 I- + S4O62-ox. + red.So the reaction between potassium iodide (KI) and potassium thiosulfate (K2S2O3) is NOT possible because they both are reductors (electron donors).Iodine-Iodide complex is essentially Iodine is an oxidator, bound to a non-reacting I- ion (Iodide)
Almost yes, but it may sometimes contain Potassium iodate, Sodium iodate or Sodium iodide in place of Potassium iodide
Potassium iodide
I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion. So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Potassium molecules have been known to dissolve better than sodium molecules. One example is Potassium Chloride and Sodium Chloride thanks
ClO- (aq) +2I- (aq) +2H ions (aq) ----> I2 (s) + Cl- (aq) + H20 (l)
No, reaction
The endpoint color of sodium hypochlocrite and potassium iodide is not listed.

Iodine in the iodized salt exist as iodine salts (potassium iodide/iodate or sodium iodide/iodate).These salts are dissolved and dissociated in the organism as NaCl.
no, it is not required.
Iodine is added to salt as potassium (sodium) iodide or potassium (sodium) iodate. An iodine deficiency is a source of thyroide diseases or can lead to idiocy.

They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...
Produces Silver iodide precipitate and Sodium nitrate
