Yes. "Potassium Iodine" tablets is a colloquial - and incorrect - way of saying "Potassium Iodide" tablets.
No, potassium iodide is a white salt formula KI and is a compound. Iodine is an intense deep purple - black solid, formula I2 and is an element. Potassium Iodide is nonvolatile but Iodine is quite volatile and vapour is given off even in the solid state at room temperature.
Lugol's Iodine = 20g Potassium Iodide + 10g Iodine dissolved in 1L H2O Gram's Iodine = 6.7g potassium iodide + 3.3g Iodine dissolved in 1L H2O Recipe's taken from Flinn Scientific Catalog I have on campus. Looks to me as Gram's is just a dilute version of Lugol's. Same ratio of KI:I just less of it. Couldn't tell you much about differences in application however.
According to Kodak: For a 0.1 Normal (0.1N) solution of iodine (I2), in 1 L volume flask, dissolve 40 g potassium iodide in 25 mL water. Next, add 12.7 g iodine (I2) and dilute to 1 L. Note that a 0.1N solution is not the same as a 0.1M solution. For iodine 0.1N is 0.05M.
No reaction occurs girlsnotgrey: If you look at the periodic table for the the halogens the F, Cl, Br, I Chloride is higher up on the periodic table then Iodine. Meaning that Chlorine is more reactive then Iodine. so when Iodine is mixed with sodium chloride, Chloride will stay with sodium and there will be no reaction. NaCl(aq)+I(aq)= NaCl(aq) +I(aq) as you can see there is no reaction so you just write no reaction.
both a and b are true for iodine and radioactive iodine isotope
NO, they are different.Iodide is only one ion (I-) and potassium iodide (KI) is the salty product when you react potassium (K) and iodine (I2)

The term iodized (said usually about table salt) means that an iodine compound has been added. This is usually sodium iodide or potassium iodide, meaning the combination of sodium (or potassium) and iodine into an ionic compound.
It's the same thing. It is a solution of water that has been saturated to the max with potassium, then iodide is added (a form of iodine). So it is a potassium iodide solution.
All are sodium chloride, NaCl. Iodized salt have added iodine as potassium iodate or potassium iodide; individuals with an insufficient daily intake of iodine are idiots, as in many countries in the world.
The same, Potassium iodide
No, they are different

Tincture of iodine is a mixture of iodine dissolved in a potassium iodide solution. Iodine is the pure compound. At room temperate, iodine is quite unstable and tends to sublime. The tincture of iodine KI3 is used to stabilize iodine in certain experiments and as a reagent.
Potassium iodide
NaClWhile normal table salt is sodium chloride (NaCl), iodized salt has additives which supply iodine. These additives might include sodium iodide (NaI), potassium iodide (KI) or sodium or potassium iodate (NaIO3 or KIO3).
No, it is not correct.
