Why does sodium iodide have a yellow color?
I 2 and I − complex to form the triiodide complex, which has a yellow color, unlike the white color of sodium iodide. Water accelerates the oxidation process, and iodide can also produce I 2 by photooxidation, therefore for maximum stability sodium iodide should be stored under dark, low temperature, low humidity conditions.

What does iodide react with?
Iodine combines readily with most metals and some nonmetals to form iodides; for example, silver and aluminum are easily converted into their respective iodides, and white phosphorus unites readily with iodine. The iodide ion is a strong reducing agent; that is, it readily gives up one electron.

Can you mix iodine and salt?
People combine iodine with table salt to reduce iodine deficiency. There are many other health benefits to using iodized salt in your diet, as well. Boosts thyroid function. Your thyroid gland relies on iodine to increase the production of thyroid hormones, like triiodothyronine and thyroxine.
Is sodium iodide a strong acid?
Answer and Explanation: Sodium iodide is made from sodium hydroxide and hydrogen iodide. Sodium hydroxide is a strong base and HI is a strong acid.
What happens when you mix sodium iodide and silver nitrate?
When silver nitrate and sodium iodide are mixed in aqueous solution, they participate in a precipitation reaction to produce a cream colored precipitate of silver iodide.
Does NaI form a precipitate?
From Table 11.2 we find that NaI and (NH4)2SO4 are both soluble. Thus no precipitation reaction will occur, and there is no equation to write.
Does sodium iodide and potassium chloride form a precipitate?
Both potassium chloride and sodium iodide are soluble in water. There is no precipitate.
Is sodium iodide soluble in acetone?
1. Iodide ion is a good nucleophile and sodium iodide is quite soluble in acetone. On the other hand, sodium chloride and sodium bromide have low solubilities in acetone. As a result, the reaction of alkyl bromides and alkyl chlorides with NaI/acetone can serve as a simple test reaction as indicated below.
Is sodium iodide soluble in ethanol?

Does iodide dissolve in water?
Most iodide salts are soluble in water, but often less so than the related chlorides and bromides. Iodide, being large, is less hydrophilic compared to the smaller anions. One consequence of this is that sodium iodide is highly soluble in acetone, whereas sodium chloride is not.
What happens when sodium is reacts with water?
In what way and in what form does sodium react with water? A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction.
How does NaI dissolve in water?
Answer: NaI is an ionic compound that can dissolve in water due to the polar nature of water molecules. Iodine is made up of molecules of I2, which individually have no dipole moment (the I-I bond has no dipole as both iodine atoms have the same electronegativity).

What is sodium iodide used for?
Sodium iodide activated with thallium, NaI (Tl), when subjected to ionizing radiation, emits photons (i.e., scintillate) and is used in scintillation detectors , traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements. NaI (Tl) is the most widely used scintillation material. The crystals are usually coupled with a photomultiplier tube, in a hermetically sealed assembly, as sodium iodide is hygroscopic. Fine-tuning of some parameters (i.e., radiation hardness, afterglow, transparency) can be achieved by varying the conditions of the crystal growth. Crystals with a higher level of doping are used in X-ray detectors with high spectrometric quality. Sodium iodide can be used both as single crystals and as polycrystals for this purpose. The wavelength of maximum emission is 415 nm.
What is the radioactive salt of sodium?
Some radioactive iodide salts of sodium, including Na 125 I and Na 131 I , have radiopharmaceutical uses, such as in the treatment of thyroid cancer and hyperthyroidism or as radiolabeling tracers in imaging (see Isotopes of iodine > Radioiodines I-123, I-124, I-125, and I-131 in medicine and biology ).
What is the reaction of sodium iodide?
