Why is sodium iodide soluble in water?
NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).
Is sodium iodide a soluble salt?
Sodium iodide is a metal iodide salt with a Na(+) counterion. It is an inorganic sodium salt and an iodide salt. Sodium iodide is a water-soluble ionic compound with a crystal lattice.
Is iodide soluble 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.
Why is sodium iodide soluble in acetone?
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 Na+ with insoluble in water?
Solubility of sodium and sodium compounds At 20oC solubility is 359 g/L, in other words adequately water soluble.
How do sodium iodide and iodine differ in their solubility in water?
Iodine is only slightly soluble because of London dispersion forces. This is when electrons are more concentrated on one side of the molecule due to probabilities. NaCl is quite soluble in water because it is an ionic compound.
Which iodide salts are insoluble?
The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in water. PbCl2, PbBr2, and PbI2 are soluble in hot water. The water-insoluble chlorides, bromides, and iodides are also insoluble in dilute acids.
Is sodium sulfate soluble in water?
Sodium sulfate/Soluble in
Is sodium bicarbonate soluble in acetone?
Yes, acetone ignores bicarbonates, but if you dissolve sodium bicarbonate in vinegar, it’ll clean the sodium acetate crystals 🙂 More information about Sodium carbonate (Na2CO3).
Why in sodium chloride is soluble in water but insoluble in acetone?
Sodium chloride is an ionic molecule. There exists electronegativity difference between Sodium and Chlorine, which gives polarity to the molecule. Thus sodium chloride is polar molecule. Generally polar molecules will soluble in polar solvents and insoluble in non-polar solvents.
Is mgso4 soluble in water?
