Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.

Why double amount of potassium iodide is required for dissolving iodine?
It sounds like you're describing Lugol's iodine. It's not technically "required," it's just that's what the recipe is. Actually, in Lugol's iodine, KI is needed to improve the dissolution of iodine in water.
Why potassium iodate is added to potassium iodide in iodometry titration?
Iodometric titration means the titration of triiodide. Preparation of triiodide can be prepared by adding solid iodine to excess potassium iodide, however since iodine sublimes it is more difficult to weigh than potassium iodate. The triiodide would then need to be standardized with primary standard grade arsenious oxide. A better way is to weigh potassium iodate and add to a small excess of potassium iodide. The two ions (iodide and iodate) will also form the needed triiodide in an acidic environment. If the reagent is made fresh this way it can be used to standardize thiosulfate. Iodide iodate of known normality can also be used to titrate unknown concentrations of sulfite. For example, steam boiler treatment applications.
How many atoms of potassium are needed to react with an atom of iodine?
One to one
How many moles of potassium iodide are needed to make 750 ml of a 1.8 M solution?
1.35 mole
What Calcium and Iodine compound formula?
CaI2 . This is calcium iodide. Recall, Ca2+ and I-. Therefore, two iodine atoms are needed for every 1 calcium. The suffix also changes to -ide; this happens for all halogens.
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
What does iodized salt contain?
Iodized salt is a combination of regular table salt, sodium chloride, with a small amount of a salt of iodine, potassium iodide. Iodized salt has gained popularity in some countries because iodine is needed by the thyroid to function properly and iodine deficiency can cause the thyroid disease called goiter.
How many grams of potassium iodide will produce 750 grams of silver iodide when there is an excess of silver nitrate?
530,3 g potassium iodide are needed.

Is potassium iodide ionic or molecular?
Potassium is K1+, and Iodine is I1-. As a result, Potassium iodide is made. It's ionic becuase Potassium has a positive charge, so it needs one more electron to have its orbitals filled. Iodine on the other hand, has an electron that isn't needed. If Iodine can give up its electron, then all of its orbitals will be filled. As a result, iodine gives it's extra electron to the potassium, and they both have filled orbitals. When an electron is being given and accepted, that's called an ionic bond. So Potassium iodide is ionic.

How many iodine ions are needed to balance out a barium ion?
A barium ion has a charge of 2+ and an iodide ion has a charge of 1-, therefore, two iodide ions are needed to balance the barium ion. Ba2+ + 2I- --> BaI2
How many moles of potassium iodide are needed to make 750 ml of a 1.8 M solution?
1.35 mole
What is hydrazine iodide in?
Don't know, but what I do know is I mix Lugol's with hydrazine hydrate to get hydrazine iodide. I used this as a antiseptic solution to kill viruses as alcohol antiseptic is useless and iodine has staining properties and also cleaning. A trace concentration is used as an antioxidant for cleaning chemicals and other things I used. I also used it correctly or incorrectly to remove skin blemishes that can't be clean by ordinary means. Potassium iodide in itself doesn't work as antiseptic solution. Trace hydrazine in amino acid was found to have powerful antioxidant effects against glycation and hence is used in research, especially the histidine hydrazide, but maybe used with iodine with trace quantities of hydrazine iodide to allow iodine to be more of a reducing compound or a reductant in various chemical reaction and perhaps in removal of Advanced Glycation End products (AGE) where it is required. Most iodine are relatively unconsumable in larger amounts as iodine is more of an oxidant and it's REDOX is in compatible in humans and hydrazine iodide is used in research to find ways to allowing the body to uptake iodine in greater quantities when the REDOX are close to biological REDOX. Of course there are other alternatives such as histidine hydrazide or another hydrazine component such as aminoguanidine used in similar research, but it can't carry the iodine needed by the cells, yet iodine uptake is still limited through potassium iodide, sodium iodide, and hence the reducing the iodine is being explored as a possible ways to improve the iodine uptake to the cells by making their REDOX closer to the cells REDOX. For example if the cells's ORP is -50 mV, we have to adjust using the hydrazine iodide to get similar -50 mV, this should reduce the toxicity of the differences in the ORP, besides of course after you adjusted the pH to similar cellular conditions as well. Other scientists out there might be doing similar things, but may used hydrogen iodide instead, unfortunately hydrogen iodide is not available and a hydrazine iodide can be made from an iodine solution being more convenient and it seems the iodine solution is more stable then the hydrogen iodide. That's the best I can say about this, which I have no idea what they are used for, but this is at least what I am currently looking into. The compound of hydrazine iodide however, in a biological systems may lead to a thiamine deficiency and hence, the addition of this may also be needed.
